Gearboxes such as the WG, V, or SR series provide the mechanical advantage to make hand operation possible for most valves. Where automated process control is needed or torque requirements are too high for manual operation to be practical, these gearboxes can be coupled to MX, L120 or SMB actuators.
V series bevel and SR series spur gearboxes offer an extensive range of thrust and torque outputs for multi-turn applications such as gate and globe valves, and slide gates. The V and SR series include input adapters for motorizing with Limitorque MX, L120, or SMB electric actuators, providing simple conversion to motorized operation.
WG series and HBC series worm gearboxes offer an extensive range of torque outputs for quarter-turn applications such as butterfly, ball, and plug valves, and dampers. The WG and HBC series can be motorized with Limitorque MX, L120, or SMB electric actuators, accommodating a wide range of torque and stroke time requirements.
