The DH6i fire hydrant pressure reducing valve is the latest evolution of the DH range of hydrant reducing valves. As with all the predecessors the valve has been fully designed and tested in accordance with BS5041. This new design has been developed under our approved ISO 9001 design system. The 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.
This range of valves are manufactured in a variety of materials, which include Gunmetal, Stainless Steel, Duplex Stainless Steel and Titanium. The valve has a flanged inlet to customers requirements, and a quick release instantaneous coupling outlet. The Inlet pressure is 20.0 Barg maximum with a reduced pressure range of 4.0 to 8.0 Barg
