Humphrey offers design engineers and plant technicians a variety of standard and specialty 2-, 3- and 4-way Manually Operated Valves to solve simple pneumatic work station problems and application challenges.

Humphrey Pneumatic Manual Valves are offered in many operator styles including Lever, Toggle, Pushbutton, Palm Button, Knee and Foot actuators.  Functions include 2-Way, 3-Way and 4-Way in either spring return or detented actuation (momentary output or maintained output), and in port sizes from 10-32 UNF to 1/2 NPT.  Couple miniature manual valves with larger Air Piloted Humphrey Valves located remotely, and save on compressed air consumption and work station space.

The Humphrey line-up is highlighted by our Classic Diaphragm-Poppet Series.  These manual valves feature Humphrey’s promise: Valves that “Cannot Stick, Will Not Leak.”  Unlike spool valve types, the unique diaphragm-poppet design has no sliding seals to stick or wear, even in poor air conditions. And many users take advantage of the Diaphragm-Poppet design to ensure their media remains clean, unaltered.  Brass bodies are options for alternate gases and liquids, and corrosive environments.  Enjoy unmatched performance and reliability.

TAC miniature pneumatic logic components include a variety of toggle and pushbutton valves in 2-, 3- and 4-way function.  Pushbutton valves are designed to accept optional foot, knee, or finger tip manual operators. 

Easy navigation to final valve selection(s), solid model CAD files, product specifications and support information is available via our Online Catalog.  Should assistance be needed, our application and engineering staff is ready to answer your questions, provide selection assistance and discuss any special requirements or modifications not found in the catalog.
