[. . . ] · All Rights Reserved 1 EN0B-0411GE51 R0506 ML6420A3072 Electric Linear Valve Actuator OPERATION General The drive of a synchronous motor is converted into linear motion of the actuator stem by using a spur gear transmission. The actuator stem is connected with the valve stem by a button keyed retainer connection. Installed microswitches switch off the actuator 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. Order number: 43191680-005 Electrical Installation The actuator is delivered with a pre-installed cable gland PG13. 5 (21. 2 mm) and two additional knock-outs for PG11 (18. 9 mm) and PG13. 5. Auxiliary Potentiometer Auxiliary potentiometers are available for on-site mounting. They can be used as feedback potentiometers and/or to provide remote indication to the valve position. Order number: Order number: 43191679-011 (10 k) 43191679-012 (220 ) High-Temperature Kit The High-Temperature Kits are necessary for applications between 150 and 220 °C medium valve temperature.
