Outlet Worm Gear Head

This worm gear operator pairs a worm and worm wheel inside an enclosed square housing to multiply the torque applied at the handwheel, allowing large or high-pressure valves to be opened and closed with modest effort. The gearing also provides smooth, controlled travel and a self-locking action that holds the valve securely in position. The sealed housing protects the internals from dirt and moisture, making the unit a reliable choice for butterfly and other quarter-turn or multi-turn valves.
