ABSTRACT:
A disk valve construction having relatively movable face to face disk upstream of a sleeve member at an outlet chamber of the valve. The sleeve member includes a truncated conical portion to produce a desired pressure drop, while, at the same time reducing the turbulence of the fluid flow during operation of the valve. The sleeve member is maintained in position by way of pressure of the fluid, thereby avoiding the necessity of epoxy to hold the sleeve member to the valve body. The sleeve can be provided with an end wall with a discharge opening of a predetermined size at the downstream end of the sleeve for producing a predetermined fluid pressure drop.
