Bermad IR-470-54-bKU Flow Control Valve



Bermad IR-470-54-bKU Flow Control Valve

The Bermad Normally Closed, Flow Control Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve that limits system demand to a constant preset maximum flow rate.

It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.

The 3-Way Hydraulic Relay Valve (3W-HRV) hydraulically connects the Flow Pilot to the Valve Control Chamber. Pressure Differential across the Orifice Assembly is in direct proportion to demand. The FP continuously senses and commands the Valve to throttle closed should demand rise above pilot setting. The 3W-HRV switches upon pressure drop command, directing line pressure into the control chamber, and thereby causing the main Valve to shut. The 3W-HRV also features local

Manual closing.
