1 90G-21 90A-21 UL & ULC Listed Globe or Angle Pattern Proven Reliable Design Available in Cast Bronze, Ductile Iron and Cast Steel Accurate Pressure Control In Line Service Grooved Ends (1-1/2 - 8 )Cla-Val 90-21 Pressure Reducing Valves are indispensablein any fire protection system. Available in globe ( 90G-21 ) andangle patterns ( 90A-21 ), our diaphragm actuated design isproven to be highly reliable and easy to maintain. Globe andangle pattern valves feature a full range of valves are also available in a variety of materialoptions. Epoxy coating is strongly recommended for all firesystem valves (excluding bronze valves).

3 Thevalves pilot control system is very sensitive to slightdownstream pressure fluctuations, and will automaticallyopen or close to maintain the desired pressure downstream pressure can be set over a wide rangeby turning the adjustment screw on the CRD pilotcontrol. The adjustment screw is protected by a screw-on cover, which can be sealed to discourage ApplicationUnderwriters Laboratories requires the installation ofpressure gauges upstream and downstream of the Pres-sure Reducing Valve. A relief valve of not less than 1/2 inch in size must alsobe installed on the downstream side of the pressure con-trol valve.
