Fire pressure switch, alarm valve pressure switch, explosion-proof pressure switch, ZSJY pressure switch

I. Explosion-proof Pressure SwitchPurpose:
The pressure switch is a key component in automatic sprinkler systems, often used in conjunction with wet alarm valves, deluge valves, pre-action systems, etc., to transmit alarm signals. When connected to the fire pump control box, it can activate the fire pump.

II. Features of Explosion-proof Pressure Switch:
The pressure switch has a rectangular, bread-like shape with an attractive and aesthetically pleasing appearance. The body is made of high-quality brass, and the housing uses ABS high-strength engineering plastic. It operates sensitively and reliably, with a long product lifespan.
