Abstract
A valve assembly has a housing forming an outlet, having an axis, and secured on a support surface. A support block in the housing has a pair of inlet ports adapted to be connected to pressurized feed lines and an output port communicating with the outlet of the housing. A valve cartridge sitting on the support block includes a casing centered on the housing axis and having a rear end formed with axially rearwardly directed bumps and a stack of disks in the casing including an end disk formed with ports provided with seals projecting axially forward past the casing to the respective support-block ports and at least one valve disk displaceable to vary flow from the inlet ports to the outlet port. A stem projecting axially rearward from the casing is displaceable to move the valve disk. A retaining sleeve formed with a screwthread threadedly engaging the housing is centered on the axis, surrounds the valve cartridge, has a front end bearing directly on the support block, and has a shoulder bearing axially forward on the bumps of the casing and pressing the seals into the support-block ports so that the casing is retained by the sleeve on the support block. A handle is mounted on the stem outside the housing.
