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”.
