Product Description
The BERMAD Top Pilot Pressure Reducing Control Valves with solenoid control offer top performance, compact design, and intuitive plug-and-play operation, thanks to an innovative integrated pilot, equipped with a high-resolution adjustment dial for easy, quick & accurate calibration.
Model 22T-55-3W-X reduces higher upstream pressure to a calibrated constant downstream pressure, regardless of flow fluctuations, and opens fully when line pressure drops below setting. The valve opens & shuts in response to an electric signal.

Technical Data
Operation
The Pressure Reducing Pilot 1 commands the Valve to throttle closed should Downstream Pressure P2 rise above the setting and to open fully when it drops below the setting. The Integrated Trio Selector 2 enables manual closing and opening override or electric control, in which the solenoid 3 connects valve control chamber 4 with line pressure to throttle close the valve or vents it through the pilot to open the valve
