APR3 Series High Flow Pressure Reducing Valve is a control system pressure reducing valve for high flow fluids, 

This series of pressure reducing valves can withstand an inlet pressure of 3600 psig (248.2 bar), 

Works well to control pressure behind the valve when flow rates change significantly, 

Works well in situations where primary pressure reduction is required to a low-pressure system,
