  • VALVE ASSEMBLY AND LIMIT SWITCH ASSEMBLY THEREFOR
    Publication number: 20180252333
    Abstract: A valve assembly includes a valve, an actuator for opening and closing the valve, and a positioner for controlling the actuator. At least one limit switch assembly is mounted between the positioner and the actuator. The limit switch assembly connects the actuator and positioner so that movement of the actuator valve is conveyed to the positioner through the limit switch assembly. The limit switch assembly is configured to provide a limit signal when the valve is in one or more limit positions. The limit switch assembly has a calibration mechanism for adjusting the one or more limit positions using an input member accessible from outside of the limit switch housing when the limit switch is installed in the valve assembly.
