Replacement Non-Metering Cartridge Kit

This cartridge has been adapted to provide a relatively inexpensive non-metering cartridge for the Tempus II valves. When this cartridge is used, it is necessary to utilize the looped operating lever assembly and cap nut from the old brass Tempus cartridge being replaced,.along with the existing push rods and push rod ends. New operating levers, push rods and push rod ends are no longer available. The old Tempus II valve received a minor change in its casting during its last few years of production. This change made the opening at the top of the cartridge bore slightly larger than the previous casting. As a result, the older castings will not accept the #19811 retro-fit cartridge until the upper "O" ring is moved against the small rim at the top of the cartridge. Once this is done, the retro-fit cartridge can be pushed down into the body. The rim at the top of the cartridge compresses the upper "O" ring of the cartridge against the valve body forming the upper seal. It is important that when the cap nut is screwed onto the valve body, it is not tightened to the point where it shears this "O" ring. Only very moderate tightening is required to seal the cartridge.
