PRODUCT INFORMATION
Pressure Relief/Sustaining Valve IR-430
The Bermad Model IR-430 Pressure Relief/Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure; when installed as a relief or circulation valve, it relieves line pressure in excess of preset.
APPLICATIONS:ֺ
- Downhill Supply Lines Emptying Prevention
- Pressure Zone Prioritizing
- Line Fill-Up Control
- Pump Overload and Cavitation Protection
- Pump Minimum Flow Safeguard
- Excessive Line Pressure Protection
