ST500X pressure relief/holding pressure valve
Relief valve: feed pipe can be more than guiding value for the pressure release valve, and maintain in the tube under pressure in a safe setting, in order to prevent the pipe pressure or sudden (SURGE) damage to piping or equipment.
, can be used in high building fire test cycle system of pressure, in order to prevent the water pressure is too high resulting in systemic risk.
Holding pressure valve: can maintain the main valve upstream water supply pressure in more than a certain value, in order to ensure the pressure of the main valve upstream water supply area.
Emergency open valve: packed in fire fighting, at the pump outlet when pressure at the pump outlet risen to more than a certain value when the valve is opened immediately.
Pressure rating: PNl10, PN16, PN25
Diaphragm type: from 50 mm ~ 150 mm
