ProControl™ Valve Series
Delivers Precise Variable Flow Control
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.
Humphrey ProControl™ proportional valves are available in five sizes and feature:
- Low hysteresis
- Excellent turndown ratios (resolution)
- Cycle repeatability
The advanced ProControl™ Servoid Series delivers extremely precise control and high output flow settings, and has become a standard in critical care patient ventilation equipment.
Use ProControl™ Valves to control flow:
- Dynamically: for continuous high-frequency adjustments (closed-loop responses)
- Incrementally: with pre-determined low-frequency adjustments within each cycle
- Selectable: cycle-to-cycle selected output flow, as prescribed

Miniature Proportional Solenoid Valves
Humphrey’s PV3 and PV10 series of miniature solenoid valves deliver variable flow control of compressed air or inert gas. The 10-32 UNF ported PV3 and PV10 are available as inline or subbase mounts with low hysteresis, excellent resolution and cycle repeatability.
Small Proportional Solenoid Valves
The 1/4 NPSF PC30 ProControl™ proportional solenoid valves deliver variable flow control of compressed air or inert gas from an input current. The rugged, compact PC30 series is flexible and may be customized with unique requirements for specific applications.
Features:
- Low hysteresis
- Excellent resolution
- Inline or subbase mount
- High flow up to 225 SLPM
Large Proportional Solenoid Valves – Servoid Series
Balanced Servoid and Unbalanced Servoid Series proportional valves provide superior pressure and flow control performance of inert gases. ProControl Servoid ™ utilizes a frictionless, flat-spring armature cartridge to achieve excellent characteristics and long life with a compact construction. With this superior design, we recommend our factory assistance to calibrate Servoid Series valves to your precise requirements.
Balanced servoids offer:
- Stable performance regardless of upstream pressure fluctuations
- Ultra-low hysteresis and excellent turndown ratios
- Precise flow rates of up to 200 SLPM at 11 PSI
- Single solenoid, normally closed 2-port valve function
Unbalanced servoids specs include:
- High flow design
- Low hysteresis and excellent turndown ratios
- Excellent repeatability
- A flow rate of 170 SLPM at 1.7 PSI
Proportional Solenoid Valve Driver
Consider the convenient Humphrey PCD Proportional Valve Driver for valve testing or workbench use. ProControl™ PCD produces appropriate current control and power supply hook up to drive any proportional valve of 1 amp or less either manually or from a signal from any data acquisition source. Additionally, drive proportional valves through PWM or constant current signals with PCD.
Features:
- Control input options: 0 to 5v, 0 to 10v, 4-20mA, or manual
- Presets for Humphrey ProControl Valve models: PV3, PV10, PC30, or Servoid models,
- Connector: screwless, push-button clamp
- User interface: LCD Screen
- Industry-leading LCD readout
- Setup/installation instructions included
