PRODUCT INFORMATION
Bermad IR-430-50-R Pressure Relief/Sustaining Valve
The Bermad Model IR-430-50-R is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure, regardless of fluctuating flow or varying downstream pressure.
This valve either opens or shuts in response to remote pressure commands. When installed offline, the Bermad Model IR-430-50-R relieves line pressure in excess of preset.
APPLICATIONS

TECHNICAL DATA
OPERATION
The Pressure Sustaining pilot commands the Valve to throttle closed should upstream pressure drop below pilot setting, and modulate open when it rises above pilot setting. The Hydraulic Relay Valve closes upon receiving a remote pressure command, shutting the main Valve. The downstream cock valve enables manual closing.
