Van giảm áp Cla-val 90-21

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 modulate to maintain the desired pressure setting. The downstream pressure can be set over a wide range by turning the adjustment screw clockwise (increase pressure) or counter clockwise (decrease pressure) on the CRD pilot control. The adjustment screw is protected by a screw-on cover, which can be sealed to discourage tampering.
