A faucet for controlling the dispensing of liquids includes a valve body havinmg a valve chamber with a valve element movable between first and second positions for controlling flow between an inlet and the outlet. An operating stem extends from the valve element to a position exteriorly of the body through a bonnet connected to the body. A safety -type cam actuator is joined to the stem and is pivotally movable to selectively move the valve element between the firsr and second positions if it is first moved inward radially of the stem. Wall forming portions extending outwardly from an insert located between the bonnet and the body to define guide surfaces closely adjacent the stem and the cam actuator to prevent undesired tilting of the stem and the cam actuator.
