Humphrey ProControl™ Proportional Valves
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
