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.
