QB3H High Pressure Valve Series

The QB3H high pressure valve is capable of operating at high pressures up to 500 PSI (34.47 Bar) and high forward and relief flows up to 50 SCFM (1416 LPM).

The QB3H consists of two solenoid valves which add or subtract pressure to the pilot of an integrated volume boosting regulator.

An internal stainless steel pressure sensor measures the high pressure output of the integrated volume booster and sends this signal to the on-board controller. 

This controller then modulates the two solenoid valves to match the integrated volume booster’s output pressure to the user requested command signal.

Aluminum bodies are standard and all brass body units are oxygen cleaned at the factory for the direct control of O2 into any process.
