Cla-Val 90G-21 (globe) and 90A-21 (angle) PressureReducing Valves are indispensable in any fire protectionsystem. Our diaphragm actuated design is proven highlyreliable and easy to maintain. We offer both a globe orangle pattern with a full range of adjustments. These valvesare also available in a variety of material options. Epoxycoating is strongly recommended for all fire system valves(excluding bronze valves). The 90G-21 and 90A-21 can besupplied with optional internal and external epoxy coating ofthe main valve wetted surfaces.

4 X46A Flow Clean Strainer

Cla-Val 90G-21 (globe) and 90A-21 (angle) PressureReducing Valves automatically reduce a higher inlet pres-sure to a steady lower outlet pressure regardless ofchanging flow rate and/or varying inlet pressure. Thevalves pilot control system is very sensitive to slight down-stream pressure fluctuations, and will automatically openor close to maintain the desired pressure setting. Thedownstream pressure can be set over a wide range byturning the adjustment screw on the CRD pilot control. Theadjustment screw is protected by a screw-on cover, whichcan be sealed to discourage tampering.

Typical ApplicationUnderwriters Laboratories requires the installation of pressuregauges upstream and downstream of the Pressure ReducingValve. Also, a relief valve of not less than 1/2 inch in size must be installedon the downstream side of the pressure control valve. Adequatedrainage for the relief valve discharge must be provided.
