Pressure Sustaining Valve IR-430-RXZ
The BERMAD Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.
- Line Pressure Driven, Hydraulically Controlled
-Prioritizes pressure zones
-Controls system fill-up
-Opens fully upon line pressure rise
- Metal Control Accessories
-Damage resistant
-High pressure rating
- 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 performance
-Progressively restrains valve closing
-Prevents diaphragm distortion
- Simple In-Line Inspection and Service
Typical Applications
