Pressure Relief/Sustaining Valve IR-430-50-R
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. It either opens or shuts in response to a remote pressure commands. When installed offline, the BERMAD Model IR-430-50-R relieves line pressure in excess of preset.
- Hydraulic Pressure Control
-Line pressure driven, hydraulically controlled on/off
-Sustains supply pressure and controls system fill-up
-Relieves excess pressure protecting pump and system
- Advanced Globe Hydro-Efficient Design
-Unobstructed flow path
-Single moving part
-High flow capacity
- Fully Supported & Balanced Diaphragm
-Requires low actuation pressure
-Excellent low flow regulation performances
-Progressively restrains valve closing
-Prevents diaphragm distortion
