Δ The KARFAR model GAX742X safety pressure relief / sustaining valve is popularly used in pipeline system of high-rise buildings, mining industry, pharmaceuticals and foodstuff industry etc. It quickly response & release in response to pressure wave. It prevents damage on the pipeline and equipment from rapid pressure increase. 
It is especially suitable for fireman system of high-rise buildings to release over pressure. It can also be installed behind reducing valves to maintain a safe and normal pressure. 
Δ It can maintain a precise stable safe pressure.
 In case of excessive pressure, the valve will be fully opened for pressure release; The closing speed is adjustable; The actuator Diaphragm/piston extremely minimizes the lagged operation; This valve can be mounted at any location in the same system without changing the preset pressure of the pilot; Maintenance and examination on the valve can be done without disassembling it from pipeline.
