Humphrey direct acting and pilot operated pneumatic solenoid valves offer design engineers a variety of efficient, high flow 2 way, 3 way and 4 way types. Our valves cover nearly any need, whether media is compressed air, vacuum, and inert gases. Leading manufacturers choose Humphrey solenoid valves based on our compact, efficient and reliable designs, our application experience, and our control of manufacturing processes.

All models are produced with precision machined or molded valve bodies, achieving close tolerance sealing surfaces and the industry’s lowest leak rates. Many models deemed bubble tight in application. Direct acting valve types are highlighted by our compact, fast switching, Balanced Poppet designs. These multi-purpose valves ensure stable, reliable performance regardless of supply pressure or pressure fluctuations, or how the valve is piped (normally closed or open, diverting, selecting, etc).

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.

ADDITIONAL PNEUMATIC SOLENOID INFORMATION

Pneumatic solenoid valves can be categorized into two basic types, Direct Acting and Pilot Operated, each with characteristics and advantages, depending on your requirements.

Direct Acting Pneumatic Solenoid Valve advantages: 
      *  Capable of operation under a full pressure range, including low pressure and vacuum.
      *   Simple, reliable construction with few parts. Low cost.
      *   More tolerant in poor or unstable media conditions.
      *   Versatile, and valves can be tailored to specific applications.

Pilot Operated Solenoid Valves use a Direct Acting Solenoid Valve as a pilot operator. The pilot operator functions to shift a larger directional control valve of piston poppet or spool design. Pilot Operated Pneumatic Solenoid Valves advantages:
      *  Designed primarily for efficient control of air cylinders & air actuators.
      *  Achieves high flow capacity relative to physical size.
      *  Consumes less current (amperage) relative to flow capacity.
      *  Many configurations to select from, particularly in four way functions.

Other industry terms for Pneumatic Solenoid Valves are Solenoid Air Valves, Direct Acting Solenoid Valves, Direct Operated Solenoid Valves, Direct Solenoid Valves, Air Pilot Operated Solenoid Valves, Solenoid Operated Directional Control Valves, Directional Control Solenoid Valves, General Purpose Solenoid Valves, 2 Way Solenoid Valves, 3 Way Solenoid Valves, and 4 Way Solenoid Valves.
