Cla-Val 90G-21 (globe) and 90A-21 (angle) pressure reducing valves automatically reduce a higher inlet pressure to a steady lower outlet pressure regardless of changing flow rate and/or varying inlet pressure. The valves’ pilot control system is very sensitive to slight downstream pressure fluctuations and will automatically open or close to maintain the desired pressure setting. This downstream pressure can be set over a wide range by turning the adjustment screw on the CRD pilot control.
