In valve wings used in process systems, various operators may be used for direct or remote control of the milk. The most commonly used operators are either manually or by an engine. Handles are fitted with a wheel or hand lever, which are connected directly to the stem of the milk through a gearbox. With the movement of the stem of the milk as a 90 degree arc, the milk is opened or closed.
