[. . . ] · All rights reserved EN0B-0481GE51 R1206 ML7420A6025 ELECTRIC LINEAR VALVE ACTUATOR OPERATION General The drive of a synchronous motor is converted into the linear motion of the actuator stem by a spur gear transmission. The actuator stem is connected with the valve stem by a buttonkeyed retainer connection. An integrated spring package limits the stem force in either direction to a factory-set value. The actuator switches off precisely when the specified stem force is reached. Accessories Auxiliary Switches The actuator can be equipped on site with an auxiliary switch unit with two switches. Their switching points are adjustable over the full length of the actuator stroke. The switches can be used to switch pumps or to provide remote indication of any stroke position.
