Cla-Val Pacific's 750-60 Fire Hydrant Pressure Relief Valve is a hydraulically operated, pilot actuated automatic control valve for pressure relief service. The main valve is made of 316L stainless steel with only one moving part, an elastomeric liner. The valve has a female fire hose connection on the inlet side of the valve and male hose on the outlet side. The valve is available for 2 1/2" or 4" threaded end connections.
The Cla-Val Pacific Fire Hydrant Pressure Relief Valve will open when inlet pressure begins to exceed the preset pressure and will allow enough flow to maintain that inlet pressure. The valve will modulate to exhaust line pressure to keep it below the set point maximum. The set point is adjustable over the entire pilot spring range.
