Description
These heavy duty, spring closing solenoid valves are
suitable for control of ammonia and other common refriger-
ants, certain oils and other fluids approved for use in
refrigeration valves. They weld directly in the line and do
not require flanges. The Type S4W are pilot operated valves
using upstream pressure for the moving force, and require a
minimum of 0.21 bar (3 psi) pressure drop to fully open.
The valves are normally closed.
