Cla-Val 90G-21 (globe) and 90A-21 (angle) Pressu

Reducing Valves are indispensable in any fire protectio

system. Our diaphragm actuated design is proven high

reliable and easy to maintain. We offer both a globe oangle pattern with a full range of adjustments. These valve

are also available in a variety of material options. Epox

coating is strongly recommended for all fire system valve

(excluding bronze valves). The 90G-21 and 90A-21 can b

supplied with optional internal and external epoxy coating

the main valve wetted surfaces.

Cla-Val 90G-21 (globe) and 90A-21 (angle) Pressure

Reducing Valves automatically reduce a higher inlet pres-

sure 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 down-

stream pressure fluctuations, and will automatically openor close to maintain the desired pressure setting. The

downstream pressure can be set over a wide range by

turning the adjustment screw on the CRD pilot control. The

adjustment screw is protected by a screw-on cover, which

can be sealed to discourage tampering.

Typical Application

Underwriters Laboratories requires the installation of pressu

gauges upstream and downstream of the Pressure Reducin

Valve.

Also, a relief valve of not less than 1/2 inch in size must be installeon the downstream side of the pressure control valve. Adequa

drainage for the relief valve discharge must be provided.
