Drain valves and systems HD Fire Protect A, H2, H3, DSK, MJC, PSV, etc.

The HD Fire Protect drain valve is a high-speed differential diaphragm valve. The drencher valve is used to control the flow of water in drencher, pre- and foam systems. The valve is kept closed due to the water pressure in the system located in the filling chamber, so the exhaust chamber and the pipeline of the system remain dry. In fire conditions, when the pressure relief system is triggered, it is discharged from the filling chamber, which leads to the opening of the drain valve. The drain valves and HD units are UL certified.
