Humphrey Products is a valuable resource for leading-edge pneumatic and fluid control valves and valve systems. For well over a decade, Humphrey has been helping companies discover the benefits of an engineered solution.

Product Lineup

Pneumatic Solenoid Valves

Humphrey Pneumatic Solenoid Valves

Pneumatic solenoid valves are categorized into two basic types, direct-acting and pilot-operated. Both offer specific characteristics and advantages to meet your application requirements.

  • Miniature 2 & 3 Way Solenoid Valves
  • Small 2 & 3 Way Solenoid Valves
  • Large 2 & 3 Way Solenoid Valves
  • Small 4 Way Solenoid Valves
  • Large 4 Way Solenoid Valves

Inert Solenoid Valves

Humphrey Inert Solenoid Valves

Humphrey iDP inert Diaphragm-Poppet Solenoid Valves are designed to control difficult media, including bodily fluids, cleaners, reagents, and aggressive fluids. Our iDP is constructed of materials suitable for fluids at elevated liquid temperatures as well.

  • iDP Valves (300 Series)
  • iDP Valves (350 & 370 Series)
  • iDP Proportional Valves (390 Series)

Proportional Solenoid Valves

Humphrey Proportional Solenoid Valves

ProControl™ Valve Series

Proportional Control Solenoid Valves deliver variable output flow control from corresponding input current to its solenoid. The compact design of Humphrey’s ProControl™ Series is an excellent addition to any device or equipment and offers flexibility, precise control of flow, and economic advantages not available from on/off solenoid valves.

  • Small 2-Port Proportional Solenoid Valves
  • Large 2-Port Proportional Solenoid Valves
  • Proportional Solenoid Valve Driver

Inert Proportional Solenoid Valves

Humphrey Inert Proportional Solenoid Valves

The iDP Series of aggressive media solenoid valves has expanded. The diaphragm isolated 390 series 2-port proportional valve delivers a variable output flow of aggressive chemicals and cleaning fluids from a corresponding variable input current to its solenoid.

Similar to the 350 series ON/OFF direct solenoid valve in flow, size and shape, the 390 is the first of its kind in proportional control. For example, users of the 390 Series may now control liquid chemical flow “rate” under variable pressure conditions, or may vary the chemical dilution when mixing with water.

  • iDP 390 (inline)
  • iDP 391 (manifold)

Air Piloted Valves (Air Operated Valves)

Humphrey Air Piloted Valves (Air Operated Valves)

Humphrey offers design and plant manufacturing engineers, a variety of standard and specialty 2-, 3- and 4-way Air Piloted Valves that will address most any application, even the more difficult challenges other manufacturers cannot.

Operate Humphrey Air Piloted Valves with smaller, more efficient piloting valves located remotely, or coupled to outputs of work valves when a simultaneous function is needed. Link your pneumatic automation to auxiliary process control by pilot operating alternate media, vacuum, or very clean, high integrity air.

  • Small 2 & 3 Way
  • Large 2 & 3 Way

Manual Valves

Humphrey Manual Valves

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. 

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

Mechanical Valves

Humphrey Mechanical Valves

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.

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

Quick Exhaust Valves

Humphrey Quick Exhaust Valves

Humphrey’s versatile, Super Quick Exhaust valves redirect the exhaust or expulsion of compressed air to a high flow piped third port. Their primary purpose is to enhance the performance and life of air cylinders and air actuators by quickly sensing upstream pressure differential and redirecting downstream exhausting air.

Shuttle Valves

Humphrey Shuttle Valves

Shuttle valves allow compressed air to flow from one of two sources, delivering each path to its common out port. Typical applications include function controls from multiple locations and introducing various pneumatic media or pressure.

Check Valves

Humphrey Check Valves

Check valves allow compressed air to flow in one direction and prevent reverse flow. These one-way valves are used in applications where backflows are not permitted or must be redirected. Check valves are available in 10-32 UNF and 1/8 PIPE ports from the miniature TAC Series. Our “Humphrey Quick Exhaust” valves become excellent check valves by plugging the exhaust port.

Pressure Regulation

Humphrey Pressure Regulators

Humphrey features the ProControl™ Electronic Pressure Regulators to provide exceptional closed-loop downstream pressure control.
Incorporating a dual proportional valve approach, the analog circuitry compensates for dynamic changes in downstream pressure. Our exceptional design controls input compressed air pressure to its exact desired output pressure.

  • ProControl™ Electronic Pressure Regulators
  • TAC Miniature Pressure Regulator
