Cla-Val Models 90-01 and 690-01 Pressure Reducing Valves automatically reduce higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. Each valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. When downstream pressure exceeds the pressure setting of the control pilot, the main valve and pilot valve close drip-tight.

Model 90-01 is the full port version, while Model 690-01 is the reduced port version of Cla-Val’s iconic Pressure Reducing Valve.
