Parker solenoid valve S4W series

These heavy duty, cast steel bodied (ASTM No. A352 Grade LCB), spring closing solenoid valves weld directly in the line and do not require flanges. They are for control of Ammonia R-12 R-22 and R-502 other common refrigerants, certain oils and other fluids approved for use in refrigeration valves. The Type S4W are pilot operated valves using upstream pressure for the moving force, and require a minimum 0.21 bar (3 psi) pressure drop to fully open. It is advisable to install a strainer upstream of each S4W valve to prevent entrance of foreign material into the valve and the rest of the system. The Type RSW strainer can be welded directly to the Type S4W inlet.
