CLA-VAL减压阀规格描述如下:

Cla- Val 90G-42 (globe) and 90A-42 (angle) Pressure
Reducing Valves are indispensable in any fire protection
system. Our diaphragm actuated design is proven highly
reliable and easy to maintain. We offer both a globe or angle
pattern with a full range of adjustments. These valves are
available in cast bronze, iron or steel and all special alloy.
Epoxy coating for all system valves are supplied with internal
and external epoxy coating of the main valve wetted surfaces,
for ductile iron and cast steel only.

Function
Cla-Val Model 90G-42 (globe) and 90A-42(angle)
Seawater Service 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
open or 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.
