Cla-Val R2001602J Pressure Relief Control (RCBP)

The Cla-Val 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 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.

The Cla-Val Fire Hydrant Pressure Relief Valve will control from no flow to full open flow without any chattering or slamming under low flow conditions. There is no slip-type friction because the main valve has no bearings.
