Supply Valve Body & Piston Assembly

This corrosion resistant PEEK valve body and stainless piston is the mechanical component of the Buffer supply valve as of November 2022. It is used as a replacement component for the Water, Buffer, EtOH78 and EtOH95 supply valves. It includes the Valve Seat (Z132), Valve Spring (Z135) and Viton O-ring (Z133). This is replaced if corrosion has caused pitting or imperfections in the sealing surface within the brass valve, and does not require rewiring of the solenoid valve.
