Humphrey Products Pneumatic Valves


Humphrey is recognized as a leading producer of pneumatic products, serving organizations worldwide. Our expertise in a wide range of industries is based on technologies proven in our standard products, enabling us to create truly customized solutions for unique commercial and industrial applications. Humphrey has a wide offering of pneumatic valves including solenoid valves (direct and indirect), pilot operated valves, manual and mechanical valves, vacuum control products, and quick exhausts.

ProControl Products

ProControl Proportional Valves


The Humphrey ProControl Proportional Valves provide outstanding performance, versatility and value. The inert construction makes this an ideal choice for many types of mulit-media use. The patented frictionless flat-spring armature design results in long, trouble-free and excellent flow characteristics.

ProControl Regulator Series

Humphrey adds the ProControl pressure regulator series of products. These electronic pressure regulators provide outstanding performance, versatility and value. Designed for low volume flow rates (PCRL) or high volume flow rates (PCRH), ProControl regulators precisely sustain outlet pressure, even during dynamic changes in downstream flow rates.

Direct Acting Solenoid Valves

310/410 Valve

Humphrey’s popular valve series, the 310 and 410 Solenoid Valves, provide outstanding performance and reliability in a simple, versatile design. The pressure-balanced poppet, direct-acting operating principle provides multi-purpose functionality in a compact body.

310: 2- or 3-way, normally closed or open
410: 4-way
410-70: 4-way with integral flow controls

L310 Latching Solenoid Valve Series

Humphrey_L310The L310 Latching Solenoid Valve Series is developed from the proven advanced Humphrey technology of the balanced-poppet direct-acting solenoid valve design.  The latching technology is optimized for applications that demand low power consumption and low heat generation.

Energy Savings: Standard single solenoid valves require electrical power while holding the valve in the energized position. A 50 millisecond pulse of the solenoid fully shifts the L310 from one position to the other. Power is removed and the latching function holds the solenoid and valve positioned, thereby offering significant energy savings. The valve remains in that position until another 50 millisecond electrical pulse, of opposite polarity, is applied. This is particularly beneficial in applications where a valve remains open for long periods of time, such as remote applications, where the valve is battery powered, or where continuous power supply is limited.

HK5 Single Electric Solenoid Valve Series
The HK5 Series Single Electric (Solenoid) Valves have 10-32 pipe ports and .0020 (standard) inch² or .0014 (low power) inch² orifice.

  • Humphrey_HK5Proven diaphragm poppet design does not require lubrication and provides trouble-free performance due to no metal-to-metal contact and no sliding seals
  • Coil operation isolated from media, increasing reliability and providing multi-media use
  • Versatile plumbing, electrical and mounting features
  • Small size, lightweight and low power (standard 1.7 watt, low watt option 0.9 watt)
  • Excellent flow characteristics: Cv .05 provides 3 scfm @ 100 psig.
  • 2- and 3-way
  • Air,liquid and other gases
  • Made in the USA

Balanced Valves
Now six valves strong of 3-port and 4-port types in three sizes, Humphrey Balanced Valves offer exceptional versatility.

The Balanced Solenoid Valve Series is an universal balanced design valve, offering several benefits:

  • MULTI-PURPOSE. The Series is versatile with its many functions: Normally Closed or Normally Open; 2- or 3-way; Diverter or Selector; pressure range of vacuum to 125 PSIG.
  • MULTI-MEDIA. The Series’ balanced poppet design performs whether the media is air or inert gases, clean, dry, lubricated, or contains some airline impurities.
  • RELIABLE SHIFT, TIGHT SEAL. Internal forces generated by the pressurized media are neutralized. The shifting forces of the coil and return spring are optimized and need only seal the poppet to our tight leakage specifications.
  • HIGH FLOW CAPACITY. Internal flow path management has been maximized. Coupled with the balanced design and an optimized solenoid magnetic circuit, significantly greater flow, within a reduced overall size, has been achieved.
  • EASE of USE. All electric and pneumatic connections are on opposing surfaces, minimizing total space occupied, and simplifying mounting and connections during installation.
