G-Series Actuators are available on large butterfly and plug valves where constant high torque capability throughout the stroke is required. They feature a rack-and-pinion design and are engineered for high-flow, high-cycle applications. They are available with either manual, cylinder or motor actuator input. The G-Series line of actuators provides a long service life and features a rugged, heavy cast gear sector. Multiple bronze and stainless steel bearings provide support and minimize friction to assure smooth operation and throttling action.
