Bermad Pressure Relief/Sustaining Valves
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.
Features and Benefits:
- Line Pressure Driven Pressure Relief/Sustaining Valve
- Controls system fill-up
- Sustains upstream line pressure
- Relieves excessive pressure protecting pump and system
- Prioritizes pressure zones
- Advanced Globe Hydro-Efficient Design
- Unobstructed flow path
- Single moving part
- High flow capacity
- Fully Supported & Balanced Diaphragm
- Requires low opening and actuation pressure
- Excellent low flow regulation performance
- Progressively restrains valve closing
- Prevents diaphragm distortion
- User Friendly Design
- Easy pressure setting
- Simple in-line inspection and service
Typical 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
Bermad IR-430 Pressure Relief Valve
The BERMAD Model IR-43Q-R Quick Pressure Relief Valve is a hydraulically operated, diaphragm actuated control valve that relieves excessive line pressure when it rises above the preset maximum. It responds to a rise in system pressure immediately, accurately and with high repeatability, by opening fully. The BERMAD Model IR-43Q-R provides smooth drip tight closing.
Features and Benefits:
- Hydraulic Pressure Control
- Line pressure driven
- Long term drip tight sealing
- Long term setting stability
- Wide setting range
- Tight setting window with minimal hysteresis
- Advanced Globe Hydro-Efficient Design
- Unobstructed flow path
- Single moving part
- High flow capacity
- Fully Supported & Balanced Diaphragm
- Requires low opening and actuation pressure
- Progressively restrains valve closing
- Prevents diaphragm distortion
- Excellent low-flow regulation performance
- User-Friendly Design
- Easy pressure setting
- Simple in-line inspection and service
Typical Applications:
- System Burst Protection
- Momentary Pressure Peak Elimination
- System Failure Visual Indication
- Filter Burst Protection
