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 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
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
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 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
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
