Ross Controls 1425K77 Spring Return Servo Kit

Ross Controls 1425K77 Spring Return Servo Kit is a dedicated maintenance service kit for the 1425K77 valve in the Ross Controls 77-Series family. This SER KIT is specified for a spring-return, three-position configuration and is associated with SZ1 sizing for the 1425K77 model, enabling technicians to refresh the valve’s servo actuation in pneumatic systems. Used where reliable three-position control with spring return is required, the kit supports replacement of worn components that govern the valve’s shifting and seating, helping restore consistent actuation and response in automated equipment. The 1425K77 is documented in Ross literature as part of the 77-Series lineup, with variant kits identified to cover the different configurations of 77 valves (including related part numbers such as 1422K77 and 1424K77). As a genuine Ross Controls accessory, this kit is designed to fit the corresponding valve body and maintain interoperability within the Ross Controls ecosystem, making it a standard choice for service teams maintaining mid-size pneumatic control lines in manufacturing, material handling, and packaging environments.
