ZXZ0.12-J automatic pressure relief device in protective area
ZXZ0.12-J Gas fire extinguishing system protective zone automatic pressure relief device
It is a device that is fixedly installed in a protective area equipped with a gas fire extinguishing system and is normally closed to keep the protective area closed to a certain extent. When the fire-extinguishing agent is sprayed and the pressure in the protection area exceeds the allowable pressure, the pressure difference between the inside and outside of the protection area is used to open the movable parts, thereby releasing the pressure in the protection area.
The model of the automatic pressure relief device consists of product code, pressure relief area and pressure relief method.
