Ross Controls 422K77-Z Service Kit

Ross Controls 422K77-Z Service Kit is a base-service kit for 77 Series pneumatic valve bases, designed to refresh valve bases by providing seals and other parts needed to recondition the base (body sizes 2 and 4; 1/2" and 3/4" ported valves). This kit variant includes an E-P monitor and a reset solenoid, and lists AC voltage compatibility of 110 VAC/50 Hz or 110–120 VAC/60 Hz. The 77-Series suffix mapping indicates that "Z" denotes a 110/120 VAC solenoid, aligning with the kit's electrical actuation configuration. Manufactured by Ross Controls, this service kit is used for maintenance and rebuild of 77 Series base assemblies in industrial pneumatic systems.
