Adaptor Kit For V4043E,J; V8043J Low Pressure Steam Valves from Honeywell Home, part number 40003918-008/U. Honeywell Home carries the Honeywell Home line of residential heating controls, and the V-series and VC-series zone valves this part serves are the reference hydronic controls in North American heating.
Rebuilding a zone valve from parts keeps the body in the piping and the actuator in service. On a heating system that is already charged and balanced, replacing a seal or a cartridge is a far smaller job than cutting a valve out of the line and soldering a new one in.
Match the part to the model stamped on your valve before ordering. Zone valve bodies from the same series differ by action and by port arrangement, and the rebuild parts are not interchangeable across them.
