Parker H Series ISO Valve With Universal Manifold

Parker offers three primary valve manifold family product lines.

  • The H Micro, Moduflex, and H ISO. The selection of which valve is most suitable will depend on two major factors; the flow required shown in Cv and the design of the valve.
  • H Micro and Moduflex products are lightweight and molded of thermoplastic resin. These products are lightweight and light-duty so applications would be end of arm tooling, packaging or possibly food processing in a non wash-down location.
  • The H ISO product offers a wide range of flow and a more robust construction making it suitable for use in automotive and general-purpose industrial environments.

The H Series valve is both complex in design but yet simple in function at the same time. Many components make up the H Series valve including four primary sections, the universal manifold, end plate, valves, and the intermediate air supply module.


The Universal Manifold
 has been newly designed. This manifold is the main body of the valve which acts as the base for the valves to sit on. The manifold is the mechanism for transporting the flow of air to the valves. The manifold is also the base that contains the electrical current to power the valves. As noted above the H3 valve size does not fit this manifold without a transition plate (joiner) so currently this valve will fit the HB, HA, H1 and H2 sizes.

The End Plate comes in several styles and is the brain of the valve. This is where power (electrical signals) and communication (data) enter the valve. This end plate feeds power through the manifold and supplies electrical signals to switch solenoids on and off. Several different styles of end plates are available in collective wiring or network styles depending on how you want to control the valve.

The Valves are offered in 5 primary sizes for different flow requirements (see right sizing). HB, HA, H1, H2 and H3. This is the heart of the valve. With electrical signals on the solenoids the valves are able to shift directing the flow through the valve. Currently only 4 sizes mount on the universal manifold and the largest size (H3) needs a mating adapter or joiner known as a transition plate. Valves are available in plug-in and non plug-in style depending on how they are fed electrical signals. Plug-in are fed through the manifold an non plug-in are fed from the top of the valve bypassing the manifold.

The Intermediate Air Supply Module (IASM) serves several purposes. Acting primarily as the lungs of the valve this component is the air supply inlet. Adding additional air into the valve will increase flow to supply larger actuators. Through the use of gaskets, this module can also be used to create zones in the universal manifold. (See pneumatic zoning). The final function of the IASM is a bus extender. The valve can electrically power up to 24 solenoids but with the addition of the IASM, power can be continued through the base to power up to 32 solenoids known as “bus extension”.

What is Right Sizing?

Traditionally, customers would buy a manifold and fill it with one size of the valve. These valves were usually sized to feed the largest actuator or component in the machine. While this worked, many smaller components did not need larger more expensive valves driving them.

Today we suggest optimizing by purchasing the right size. Building the valve manifold right means determining the flow needed for each component and buying the “right-size” valve. Now that the majority of valve sizes HB, HA, H1 and H2 fit the one universal manifold base you can mix and match sizes on one base as needed.

What is Zoning?

Zoning is simply a way of dividing a manifold into sections. Each section has an independent means of air supply via an IASM and a unique gasket is used to block off the other sections. Shown below is a manifold (exploded view) divided into two zones. P1 and P2 are pressure ports for supplying air to each section.

Why Zone on Manifold?

Zoning allows you to isolate sections of the valve for varying supply pressures, increase machine efficiency by managing the machines supply pressure in sections via the valve and to enhance safety by having the ability to shut down part of the machine for maintenance or emergencies.

The H Series ISO valve is considered the core valve for Parker Hannifin’s pneumatic product line. Incredibly versatile, this ISO valve covers a wide range of flows from 0.3 Cv to 6.0 Cv (up to 3.0Cv on the new universal manifold because the size H3 valve does not yet mate to this manifold) and meets the majority of pneumatic applications. This incredibly robust aluminum, directional control valve base suits most industrial applications including automotive and in-plant general applications. Valves can be complex because this is the junction in a fluid power system where the electrical, pneumatics and data communication come Air Connectivity (for a valve to actuate pneumatic components) together. This main component (the valve) directs the flow of air and in effect controls all the pneumatic components that are connected to it.

 


Networked wiring (shown on above left) is much cleaner because the wiring is delivered with one cable from the PLC to the valve. Initially, this was a costly approach but technology has made it much more affordable. When networked data is also streamed via one cable that communicates to a PLC.
Collective wiring (shown on the above right) also know has hard wiring is the physical labor of running connections from the valve to the plc or control panel one wire at a time to make a connection. Considered an old method but it is still very commonly used today.
