Bermad IR-470-55-bKU Flow Control Valve



Bermad IR-470-55-bKU Flow Control Valve

The Bermad Model IR-470-55-bKU is a hydraulically operated, diaphragm actuated control valve that limits system demand to a constant preset maximum flow rate. It either opens or shuts in response to an electric signal.

The Shuttle Valve hydraulically connects the Solenoid or the Flow Pilot to the Valve Control Chamber. Pressure Differential across the Orifice Assembly is in direct proportion to demand. When the solenoid is closed, the FP, continuously sensing, commands the Valve to throttle closed should demand rise above setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber, thereby shutting the main Valve. The solenoid also features local manual closing.
