Plunger Operated valves achieve high flow operation from its compact body. These valves are available normally closed or open from its compact 1/8 PIPE body construction. Plunger is forgiving with built-in overstroke protection.

TAC Miniature push button valves are rugged enough to operate as a mechanical plunger valve or are ready to accept any of four different mechanical valve operators.

Roller Cam and Roller Ball Operated mechanical valves feature the classic Humphrey diaphragm poppet principle. The unbalanced, air-spring return design assures bubble-tight sealing and reliable operation in the dirtiest environments.

The rugged 2- or 3-way valves are available normally closed or normally open.

Pneumatic Solenoid Valves: The Humphrey Advantage

Humphrey Products’ pneumatic solenoid valves offer design engineers high-flow efficiency in two-way, three-way, and four-way functions. Our valves accommodate nearly any media, including compressed air, vacuum, and inert gases.

Leading manufacturers prefer the compact, efficient and reliable designs of our pneumatic solenoid valves, and they also benefit from our application experience and the control we maintain over our manufacturing processes.

All Humphrey Products’ pneumatic solenoid valve models are produced with precision machined or molded valve bodies, achieving close tolerance sealing surfaces and the industry’s lowest leak rates. In fact, many of our pneumatic solenoid valve models are deemed “bubble-tight” in application.

Total Air Control (TAC) System

Humphrey TAC System of Miniature Valves, Valve Operators, Auxiliary Components, Miniature Fittings, and Logic Accessories combine to create the industry’s most productive line up of pneumatic logic control components.

Choosing a Manual Valve for Your Application

Humphrey manual valves are compact, rugged and reliable 2, 3 and 4-way valves that provide excellent performance in industrial applications.

Line up features our rugged diaphragm poppet principle of high flow rates, reliable shifting and bubble tight sealing of 1/8 and 1/4 PIPE manual valves.

For miniature, lighter duty applications, we recommend our 10-32 UNF and 1/8 PIPE TAC series of 2, 3 and 4-way push button, push-pull and toggle valves. Versatile push-button TAC valves can be applied with or without our foot/knee or fingertip operators.

Humphrey manual operated valves include:

• Push Operated, Palm Operated
• Foot Operated
• Lever Operated
• Detented Level Operated

Choosing a Mechanical Valve for Your Application

Humphrey mechanical valves are compact, rugged and reliable 2- and 3-way valves that provide excellent performance. These valves feature our rugged diaphragm poppet valve principle of high flow rates, reliable shifting and bubble tight sealing. We recommend them in your most difficult roller can and roller ball workplace applications.

Miniature, lighter duty applications are solved with our TAC series of 2, 3 and 4-way push button mechanical valves applied with or without convenient cam or roller ball TAC operators.

Humphrey specializes in the manufacture of:

• Roller Cam Operated Valves
• Roller Ball Operated Valves
• Plunger Operated Valves

Our rugged designs are used in sequential automation with operation from work piece engagement, with high flow output in single-unit production.
