ABSTRACT:
A combined seal and actuator support for valves, in which a sleeve is engaged between the actuator shaft of the valve and the valve body to effect a seal between the shaft and body, and wherein complementally interengaged actuator means are on the sleeve and shaft to support and effect reciprocating movement of the shaft, thereby eliminating the need for expensive o-ring seals and other expensive manufacturing techniques.
