Ross Controls 422K77-A Service Kit

The Ross Controls 422K77-A Service Kit is an official Ross Controls base service kit for the 77 Series valve bases (Manufacturer Part Number 422K77-A). It is designed to recondition the valve base and includes seals and other parts required to service the base assembly. It supports body sizes 2 and 4 with port configurations of 1/2" and 3/4" valves. The kit is sold individually. Typical applications include automated industrial control systems using Ross 77 Series base-mounted valves, where periodic maintenance of the valve base is needed to preserve seal integrity and valve performance. By supplying the compatible seals and base components, the 422K77-A kit enables replacement of worn parts without discarding the entire valve base, supporting maintenance efficiency and reduced downtime. As part of the Ross Controls base service kit lineup for 77 Series, it provides a focused service option for technicians performing routine base maintenance or after component wear.
