Abstract of the Disclosure A disc-type valve assembly and method of making same. The assembly includes a valve body having a flowway with a disc- like valve element therein. A shaft has an inner portion directly rigidly connected to the valve element by a pre-stressed self- connection and an outer portion rotatably mounted in the valve body. A handle is directly rigidly connected to the outer portion of the shaft by a pre-stressed self-connection whereby the handle and shaft form a rotating body. A positioning sleeve is interposed in tight pre-stressed relation between the valve body and the rotating body for preventing relative rotation between the bodies under torque loads below a pre-determined magnitude, the positioning sleeve being yieldable under torque loads greater than or equal to that magnitude to permit such rotation.
