The Broady DH6/DH6i valve is suitable for all fire fighting applications where pressure reduction is required. A balanced inlet design ensures a constant outlet pressure, regardless of any fluctuations in the inlet pressure. The `S’ version (DH6i-S) allows the valve to work as both a landing valve, fully open in non-reducing mode, and as a standard pressure reducing fire hydrant valve. In both of these modes the valve can be fully closed using the hand wheel.
