VALVE HAVING IMPROVED CAM-TYPE ACTUATOR

摘要

A valve of the type including a body having an internal valve chamber and a valve element mounted therein for reciprocatory movement between at least two positions for controlling flow through the chamber. An operating stem having a free end extending outwardly of the chamber is arranged for moving the valve element. The stem is moved by operating means including a cap means connected to the body and extending over the free end with a cam member mounted in the cap means for rotation about an axis perpendicular to the axis of the stem. An operating shaft extends from the cam member to a position outwardly of the cap means and an operating handle is associated with the shaft for moving it between at least two positions. Additionally, latching means are associated with the handle and the cap means for locking the cam in at least one position.
