Poclain Selector Valves

Hyspecs now stocks the Poclain KV range of electronic 3 and 6 port selector valves.

Electronic selector valves are often used in a situation where a new piece of hydraulic equipment has been added to an existing machine. For instance a 6/2 way valve can divert oil from the tilt function on an excavator to another auxiliary function, at the press of a button.

Stocked valves range in size from 3/8" to 1" (BSP ports), as either 12 or 24 VDC with a manual over-ride option on all. An external drain port is drilled as standard, which allows higher pressure and/or flow in most cases. This port can be plugged if 
not needed. All valves are open on changeover.

Specification Information:












3/8" BSP, 12/24 VDC





1/2" BSP, 12/24VDC





3/4" BSP, 12/24VDC

Hydraulic Filters

Contamination is one of the few major factors with regards to hydraulic failure, though these particles can be microscopically small, they can cause damage and ultimately they could lead to system failure.

The function of a filter is to clean the oil, but the purpose of the filter is to reduce operating costs.

At Hyspecs we have a wide variety of filters that have different filtering capabilities, you can view our selection and download the price file section here.

OMT SF Suction Filter

In order to optimise the oil quality we need to install an efficient oil filtration system and make every effort to limit contamination ingress and generation. Having 'good clean oil' in return saves costs of servicing, maintenance, down time and oil changes.

Filters need to be positioned in the correct places to ensure that the motors and pumps benefit more from the clean oil than any other section in your system. A big factor in positioning is often the direction of flow.

For further information and advice call us on  1800 497 732 and talk with a sales engineer or email .


Technical Tip

Technical tip for filters.


We recommend fitting filter clogged indicators on all your hydraulic filters. These can be visual or electrical or a combination of both. They work by measuring the pressure drop across the filter element and indicating before the bypass valve setting is reached.

Without these indicators your filter elements could be clogged and the oil is bypassing with no filtration, in most cases you would unaware this is happening. If fitting clogging indicators is not possible then the filter elements should be changed periodically, the time between filter changes is dependent on the sensitivity of the components and the duty cycle of the machine.

Technical Corner - DC Electric Motor Duty Cycle

DC MotorLow voltage DC motors draw a lot of current even when the hydraulic pump is lightly loaded. For this reason our DC powerpacks have a duty cycle rating and a thermal cut out switch to protect the motor. The duty cycle is normally defined by a S1, S2 or S3 rating.

S1 is a continuous duty, S2 is short time duty and S3 intermittent periodic duty. When selecting a DC powerpack its important to know how long the motor will run under load and then the cool down period. For example our Deli units are specified as S3; 30 seconds on and 270 seconds off. We also have a full range of DC powerpacks with higher duty ratings.

SCOOBI - Self Contained Old Oil Beautifying Implement

So what's a Scoobi? The acronym Scoobi was coined by one of our service engineers a few years back and stands for "Self Contained Old Oil Beautifying Implement". The Scoobi was designed to transfer oil from one vessel to another, whilst extracting contamination from the oil in the process. Typically used for transferring old oil from a tank that needs cleaning, during system maintenance and for filling tanks in new systems. Even new oil contains contaminates so it is recommended that a new drum of oil be filtered before going into the tank. The Scoobi provides a clean and easy way of doing this.

ScoobiFeatures and Benefits
• Dual filtration in and out, 10 micron, useful for separate water and particle filtration
ensuring ultra clean oil
• Gauge for indication that filter needs changing
• Rubber tyres and contoured handgrip for manoeuvrability and easy transportation
• IP65 rated on/off switch
• Assembled from locally sourced components for ease of service
• Manufactured by Hyspecs
• Relief valve protection
• Approximate dimensions 1m(h) x 0.5m(w) x 0.4m(d)

• Transfer oil at 20 l/min
• Powered by a single phase 0.75 kW electric motor with lead & plug
• Oil is pumped via a Galtech gear pump

Nett price for the Scoobi is $2640 + GST. We currently have Scoobi's in stock and lead
time from ordering if not in stock is typically 5 working days. We also hire out our
workshop Scoobi at the rate of $50 per half day and $100 per day plus filters. Hose
assemblies can be manufactured to your specifications.

 SAFEX Anti Drop Valves

Don't Drop Your Load If Your Hose Bursts!

SAFEX valves are designed to be mounted directly to the boom and/or arm cylinders of hydraulic excavators. With the correct installation and adjustment these valves prevent uncontrolled lowering of the boom/arm cylinders in the event of a hose burst, thereby becoming part of the load holding and lowering system designed to comply with AS 1418.8 / ISO 8643. 

Each setup should be checked individually when installing, not all setups work the same on all machines, but here are some easy steps to check. The installation is quite simple yet effective contact us for more info.SAFEX

To get the protection you require without negatively affecting the machine operation, the correct balancing of the hose rupture valve and main directional valve is essential. The opening of the hose rupture valve should lag behind the main directional valve while not affecting the stability and performance of the machine. This is achieved by matching each hose burst valve to the machine on which it is installed. SAFEX manifolds are made from ductile iron with nickel plating and suitable for all excavators with flows from 30 to 600 l/min.

Hose burst valves are a mandatory requirement on all excavators over 7 tonnes when being used like a crane. 

Attach Hyspecs SAFEX valves to your excavator  and you won't risk damage or injury in the event of a hose failure. Manufactured in NZ by Hyspecs.

Hydraulic Tip

Most people over estimate the cooling capacity of the hydraulic oil tank. With a 30 degree C difference between ambient and oil temperature, a standard design steel tank can dissipate the following :
100L : 1.0 kW
200L : 1.6 kW
300L : 1.9 kW

05.16.CoolerConsidering that typically 15-20% of your input power is converted to heat, in most cases an oil cooler is required unless you have an intermittent duty cycle. Hyspecs stocks a range of air and water coolers along with thermostats, temperature switches and temperature sensors to help maintain optimum oil temperature.

Hydraulic accumulator's are pressure vessels and require protection against overpressure.


To safely service hydraulic systems with accumulators, a valve that discharges the oil in the accumulator to tank while simultaneously blocking the pump pressure is also required.

Fluid safety blocks such as our EPE BS20 have all these features in o

ne valve b

lock that screws directly into the accumulator fluid port. An additional feature that we recommend is to fit a normally open solenoid valve into the safety block. 

 During normal operation the solenoid valve is closed but when your machine is shutdown the solenoid valve opens and automatically discharges the stored oil to tank. Always check there is no pressure in the accumulator using a gauge connected directly to the accumulator fluid port before working on the hydraulic system.

Hydraulics Overheating?

As we move into summer the extra heat in the atmosphere puts more pressure on hydraulic systems.

Hyspecs recommends an operating temperature of 60 degrees Celsius. Do not test with your hand, as even touching for a split second is too hot. Instead use the temperature gauge to get an accurate reading.

Eaton recommends a maximum system operating temperature of no higher than 82 degrees Celsius. Keeping your system cool will increase the life of your system and save you money in the long run.

In a perfect hydraulic world all energy put into a system could be transferred to the job at hand, whether it is a cylinder, motor or some other hydraulic machinery. However we are lucky if we get 65-75% of the input energy turned into useful work. The rest gets turned into heat, noise and vibration.

The loss of power can be attributed to many things:

  • High pressure drop across hoses, orifices and valves
  • Mismatched motor sizes in a pressure compensated system
  • In-built inefficiencies in pumps and motors
  • Poorly designed hydraulic systems 

Try as we may to get the system 100% efficient we will never do it, so we are usually stuck with two options to overcome heat:

Air _oil _coolers2











  • Build a large oil tank to dissipate the heat. This is usually the easiest and cheapest option if designing a system from new. Hyspecs recommends a tank size of at least 2.5-3 times the maximum flow of oil in the system (not applicable to closed loop systems where the designer can get away with a much smaller tank). 
  • Install a hydraulic oil cooler cable of cooling approximately 30% of the system input power. Oil coolers typically come as either air/oil or water/oil variety. The air/oil coolers are pretty much the same as a car radiator with either an electric or hydraulic fan blowing over the fins to cool the oil flowing inside the radiator. Oil/water coolers are designed to have oil running through a large outer tube with a seperate series of smaller tubes running inside this, containing flowing fresh or slat water which carries the heat away from the oil.  Emmegi Water cooler

Check Pressure Control Devices

Visually check that pressure control devices have not been tampered with. Look for vibration or pulsation in the pressure line of the pump or motor, with erratic machine movement.

Over pressurisation can lead to costly mechanical failure in pumps, motors, cylinders and valves.

Running systems at under optimum pressure, while less likely to induce failure, can cause system to operate less efficiently. Uncontrolled decompression, thermal expansion or back flow through check valves can cause pressure spikes.

For further information and advice please call us on 1800 497 732 and talk with a sales engineer or email

Oil Reservoir - Space Saver

When you have a big pump you need a big Oil Reservoir right? Wrong.VVR-Duo -02

Standard Oil Reservoirs add weight, they increase the size of your hydraulic System and they also increase the risk of environmental contamination, but there is another option.

Hyspecs in Melbourne recently assisted a customer who wanted a hydraulic system that would operate underground. They wanted a lighter, smaller and environmentally responsible hydraulic system. Hyspecs were able to supply this customer with a Variable Volume Oil Reservoir (VVR) which met all their needs. We have eliminated the need for a 100-150L reservoir by utilising a 7litre VVR. This resulted in huge savings in oil, space, weight and ongoing operating costs while also reducing the environmental impact of a possible oil leak.

To see a VVR in action watch the video - Cylinder operating with Variable Volume Reservoir (VVR)

Energy Saving Tip: Oil Viscosity Grade

Clean hydraulic oil of the correct viscosity grade and running at optimum temperature will ensure your hydraulics work efficiently. The working viscosity range for most hydraulic systems is 15 to 100 cSt with 20 to 40 cSt being the optimum. For hydraulic oil we generally use the ISO Viscosity Grade classification which is the kinematic viscosity of the oil at 40'C. For lower working temperatures ISO VG 22 or 32 oil is recommended and for higher working temperatures ISO VG 46 or 68 oil is ideal. Hydraulic oil that's too viscous requires extra power to overcome pressure losses, oil that's too thin causes premature wear and excessive internal leakage.

For further advice speak to a Hyspecs Engineer on 1800 497 732.

Hytech - Design Doubled

Hyspecs manufacturing division, Hytech have doubled their design capabilities, and reduced their lead times.

Hytech welcomes to the team - Wendy Roberts - CAD Manifold Design Engineer.

Due to increased demand for Hydraulic manifolds, Hytech recruited Wendy as an additional designer to assist Steven Zhou with manifold designs at Hytech.

Wendy has been designing manifolds for 19 years since graduating from Coventry University in the UK with a bachelor of Mechanical Engineering. Wendy worked for UK based family business Integrated Hydraulics for 15 years (this business was bought out by Eaton), she then moved on to Hydraforce (UK) for 4 years before joining Hytech April 2015.

Hytech have been looking for ways to reduce turnaround for the manufacture of their Hydraulic Manifolds.

Why Regular Filter Changes are needed

Omt _tank _top _return _215x 313Spinona _174x 276Filters should be checked at least once a month and elements changed as per the indicators, or every 2000 hours of operation, or every 6 months whichever comes first. Fluid condition should be checked at regular intervals to maintain optimum component life. Most hydraulic failures and premature wear of components are due to oil contamination. Fluids other than petroleum, severe service cycles, very high pressures, proportional and servo valve applications require cleaner oil and better quality filters. Hyspecs recommends all filters have visual or electrical pressure differential indicators fitted so you know when to replace the filter elements. An oil particle analysis to ISO 4406 is the best way to determine your filtration effectiveness and the health of the hydraulic system. Hyspecs has oil sample kits available as well as optical oil particle monitors that can be permanently installed on your machine and interfaced with your control system.

Hydraulic Motors - how stuff works

Hyspecs provides a full range of hydraulic motor with a brief explanation of each hydraulic motor category below. Click the headings for more detailed information.

Gear Motor

Consit essentially of two intermeshing toothed gears enclosed in a common housing.

Gerotor/Geroler Motor

The H series motor uses a Gerotor while the rest of the Char-Lynn motors use a Geroler.

Piston Motor

Axial piston Motors are displacement machines in which the pistons are arranged in parallel to the axis of rotation of a cylinder barrel.

Swash-Plate Motor

In this version, the cylinder barrel is driven and, as a result, the pistons which are located and guided in the barrel rotate with it.

Bent Axis Motor

With this type of hydraulic motor, the cylinder barrel is driven by the pistons which in turn are themselves driven by the drive flange.

Wobble-Plate Motor

With this type of hydraulic motor, a so-called wobble plate is driven by the input or drive shaft.

For a more detailed description of each of these motors please visit our "How stuff works" motor series page or contact one of our Hyspecs Engineers 1800 497 732.
