Poclain Selector Valves, HYTECH-Hydraulic Manifolds

 

Hydraulic Specialties 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:

For more information download the Poclain catalogue by clicking here (see pages 37-39 (3port), 77-87(6-port)).

Our sales engineers are available to offer expert guidance on the correct method for applying these valves to your application. They can be contacted by phone (see the numbers on the contact us page) or email at info@hydraulicspecialties.com.au.

HYTECH – Hydraulic Manifolds

Hytech is the manufacturing division of Hydraulic Specialties. Hytech manufactures standard & custom hydraulic manifolds.

Hydraulic manifolds are used in conjunction with cartridge valves to provide an integrated circuit where complex functions can be performed, equal to that of most conventional control components. The manifold itself is usually some form of aluminium alloy or steel with cavities machined to accept the cartridges. The cartridges control the flow and pressure of the oil to the machines various hydraulic components such as motors and cylinders.

The advantages of this technology become clear once it is examined in more depth

1. Complex functions can be performed by one integrated circuit. This can replace many discrete components.
2. Hosing or pipe-work is greatly simplified, resulting in lower costs and fewer potential failures
3. Pressure, return and function ports can be positioned where most convenient for the end user. Customising the block to the particular machine.
4. Circuit confidentiality is enhanced, since the design cannot be easily traced without resorting to exotic X-Ray methods.
5. Installed costs are usually lower than discrete components.
6. Skilled technicians are not usually needed to install the circuit.
7. Maintenance is simplified due to rapid cartridge interchange-ability. Failure of the block itself is rare.
8. Circuit versatility industry common cavities allow cartridges with differing functions to be substituted in the block. Therefore altering the circuit to customer specific requirements.
9. The completed circuit is usually lighter than individual components.
10. The completed circuit is usually more compact than individual components.
11. Virtually any circuit can be incorporated into a cartridge block.

Hytech provides Hydraulic Specialties with standard hydraulic manifolds that are used in every day circuits, such as relief and counterbalance valves. However Hytech is also geared to provide one off hydraulic manifolds for systems seen in super yachts or factory production lines for example. Hytech can also provide original equipment manufacturers (OEMS’s) with large runs of hydraulic manifolds, fully assembled with cartridge valves and each individual unit tested before shipping to your assembly plant to be inserted into your machine. At Hytech literally no job is too big or small.

SAFEX(TM) Valve Test Video, Hardcopy/CD Pricelist, HydraForce i-Design CD

Hydraulic Specialties SAFEX^TM valves are designed to be mounted directly to the boom and/or the stick (arm) cylinders of hydraulic excavators. With the correct installation and adjustment these valves prevent uncontrolled lowering of the boom/stick 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.

To check compliance with the above standards the SAFEX^TM valve was tested on an excavator to simulate a hose burst. A ball valve connected to tank was fitted in the hose going to the boom cylinders. With the test load suspended the ball valve was opened to simulate a hose burst and the boom drop speed measured to ensure that it did not exceed 10mm/sec. For the next test the ball valve was closed and the operator moved the joystick to lower the load and the speed was measured. Then the ball valve was opened, again simulating a hose burst, and the lowering speed was measured to ensure the speed had not increased more than 100%.

We filmed this test with OSH in presence, utilising a Cable Price excavator. The valve passed the test and has been confirmed to comply with the required standards.

HydraForce i-Design CD

Now You Can Easily Create Custom Integrated Manifolds.

HydraForce's i-Design Hydraulic System Design Software allows you to create custom integrated manifolds from the very beginning design stages all the way through pricing and quoting to your customers. And the best part is that it’s FREE!!

i-Design Version 3 incorporates the schematic layout and pricing tool from previous versions with the addition of a 3D layout tool. This new feature greatly improves communication throughout the design cycle, from specification with by the OEM designer through the manifold design.

Used in house and by Hydraulic Specialties customers, i-Design gives us the ability to collaborate on a design easily and efficiently, getting the whole design completed in a fraction of the time it would otherwise take, with traditional methods.

To order your free HydraForce i-Design CD either call one of our sales engineers today by using the contact numbers listed on the Contact Us page, or drop us an email by clicking here.

Hydraulic Training Seminar Auckland, Hyspecs Mini DC Powerpacks

The next Hydraulic Training Seminar has been scheduled in Auckland for the 2nd & 3rd of September. It will be held in our specially designed seminar room at our Auckland branch, 32 Crooks Road, East Tamaki.

Book your spot on the course by downloading and filling out the registration form here.

This two-day seminar offers you an introduction into hydraulic components and their operation. Subject matter covers generic types of pumps, motors and valves and the course content will provide you with an understanding on how these components operate, are applied and conditions that may lead them to fail.

The information presented in the seminar is combined and used in a winch circuit design that is carried out with parameters provided by participants. This allows you to see an example of basic circuit design and component combinations.

Basic fault-finding is also covered to assist you with the emotions of lost money, time and production involved with on-site problem solving. Looking at problem solving from another angle can help you reduce your customer's downtime.

All topics are presented in an open forum and we welcome you to ask questions and participate in topic discussions. This provides the opportunity to hear and share real life experiences that relate to the topic being discussed. For more information on the course content download the Programme from here.

The cost of the two day course is $500 + GST and this includes all course material, lunch and refreshments for both days.

To register for the course please download the form here. Print this off and fax/post back to us as soon as possible. Alternatively just give us a call using the numbers on the contact us page or email us by clicking here. Attendee numbers are limited so places are allocated on a first come first serve basis.
