The S9A Pilot Assembly is to be used in conjunction with the S9A and S9W valves which are designed to promptly and fully open or close under conditions which make conventional solenoid valves unreliable or unsuitable.

The S9A Pilot Assembly is designed to simplify the specification and installation of an S9A or S9W. The S9A Pilot Assembly contains both the Pressure Solenoid, the Bleed Solenoid, and a strainer in a convenient package. This twin Pilot Assembly serves to admit condenser gas pressure to the piston for opening and to bleed this gas pressure to the suction line for valve closing.
