A faucet for controlling the dispensing of liquids includes a valve body having a valve chamber with an inlet and an outlet. A valve element is located in the valve chamber and is movable from a first position for blocking flow between the inlet and outlet to a second position for permitting flow between the inlet and the outlet. An operating stem has an inner end operatively connected to the valve element and an outer end located external to the body. A bonnet is included, and an insert member is rotatably connected to the bonnet and defines an opening through which the stem extends. The bonnet and insert member are secured to the body and enclose the valve element in the valve chamber. The insert is located such that no portion of the insert member is clamped between the bonnet and the body.
