SPECIFICATION

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.

These ranges 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 customer's requirements, and a quick release instantaneous coupling outlet. The inlet pressure is 20.0 Barg maximum with an option of up to 30 Barg and reduced pressure range of 3.5 to 8.0 Barg.

The reduced pressure can be adjusted via the adjusting cap; this design has several advantages over conventional adjusting screw designs. These include the fact that no threads are exposed, making it virtually impossible to damage them. It is also more robust and able to cope with accidental knocks. The valve is locked in position with a locking screw. This prevents the adjusting cap from moving, maintaining a specific reduced pressure. When the valve is in the closed position it has no water pockets. This means the valve is not affected by freezing, making it ideal for use in sub-zero conditions.
