QUICK PRESSURE RELIEF VALVE
The 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 rises in system pressure immediately, accurately and with high repeatability, by opening fully. It provides smooth drip tight closing.
TYPICAL APPLICATIONS
System Burst Protection; Momentary Pressure Peak Elimination; System Failure Visual Indication; Filter Burst Protection
FEATURES
1.Hydraulic Pressure Control
*Line pressure driven
*Long term drip tight sealing
*Long term setting stability
*Wide setting range
*Tight setting window with minimal hysteresis
2.Engineered Plastic Valve with Industrial Grade Design
*Adaptable on-site to a wide range of end connection
sizes and types
*Articulated flange connections eliminate mechanical and
hydraulic stresses
*Highly durable, chemical and cavitation resistant
3.‘Y’ shape Valve Body with "Look Through" Design
*Ultra-high flow capacity - Low pressure loss
4.Unitized Flexible Super Travel (FST) Diaphragm and
a Guided Plug
*Accurate and stable regulation with smooth
closing
*Requires low opening and actuation pressure
*Prevents diaphragm erosion and distortion
5.User-Friendly Design
*Easy pressure setting
*Simple in-line inspection and service
HOW IT WORKS
The pressure relief pilot valve [1] causes the valve to open immediately when the upstream pressure [P1] suddenly rises above the setting of pilot valve, and close slowly when the upstream pressure reduces below the setting of pilot valve. The operation test can be performed manually with the exhaust ball valve [2].
