Inner: Plastic Package 2. Outer: Plywood Case Specification: DN50--DN800 Origin: China Product Description Globe Type Double ChamberedSafety Pressure Relief / Sustaining ValveMODEL NO. :GAX742X Diaphragm Type Piston TypeSize: DN50-DN800Pressure 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) We can make higher rating according to customer request.ΔThe KARFAR model GAX742Xsafety pressure relief /sustaining valveis popularly usedinpipeline system of high-rise buildings, mining industry, pharmaceuticalsandfoodstuff 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 asafe and normal pressure.ΔIt can maintain aprecise 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.Medium applicableWater, Oil etc.Main materialCast iron, Ductile iron, Carbon steel, Stainiless steel etc.Temperature applicable≤80ºCNominal PressurePN10--PN25Nominal DiameterDN50--DN800Flange DimensionANSI B16.42, BS4504, ISO2531, ISO7005 and other standardsFace to Face LengthAPI594,BS5155, ISO5752, DIN3352 and other standards
