Safety Pressure Relief Valve is mainly in pipeline system in the fields of high-rises,mines, factories, pharmaceuticals and foodstuff etc., functioned to effect quick response and quick release to pressure wave, thus to prevent pipeline and equipments from damage due to sudden pressure rise. It is especially applicable for pressure release of fire control system in high-rises. Plus,this valve can be mounted at the lower stream of pressure reducing valve to prevent system from exvessive pressure. This valve is provided with accurate and invariant pressure of high security and smoothness.In case of excessive pressure, this valve will be thoroughly opened for pressure release; adjustable closing speed of valve; diaphragm or piston drive mechanism functioned to minimize the phenomenon of lagged operation; this valve maybe mounted at any location,and servicing and examination maybe done with no need to change pressure setting or disassemble it from pipeline. Pressure Grade: PN10(Range of Adjustment 0.3-0.9Mpa), PN16(Range of Adjustment 0.5-1.4Mpa), PN25 (Range of Adjustment 0.5-2.4Mpa) Diaphram Type: DN50-DN350 Piston Type: DN50N800
