Outline
The W series worm gear actuators are designed for multi-turn operation. They are suitable for rising stem type gates and valves that require thrust load to open and close.
Features
-
Self-locking mechanism prevents valve stem from rotating backward due to valve load.
-
Easy operation with hammer blow effect.
-
Two-piece drive sleeve configuration allows the stem nut engaged with a valve stem to be easily removed from the actuator.
-
Enclosed construction, pre-filled with “EP” additive grease, ready for use.
-
Optional local position indicator and limit switches for remote indication.
-
Compatible with actuators such as SMB, JMB, or L120.
-
Available with dual input shaft type, enhancing versatility in demanding applications.
-
Five unit sizes available, classified by output torque.
