C.U.M. Srl WG 65 Manual Rotary Actuator with Flanged High-Torque Rotary Valve

The C.U.M. Srl WG 65 is a heavy-duty, gear-operated rotary actuator engineered for operating high-torque rotary valves such as ball or plug valves in industrial pipelines. Manufactured in Italy in 2011, this actuator offers a quarter-turn (90°) rotation with a total of 56 handwheel revolutions required to complete a full open/close cycle. The unit delivers a maximum output torque of 650 kg·m (approximately 6376 Nm), suitable for demanding valve operation conditions.

The actuator is paired with a flanged rotary valve—likely a ball or plug type—designed for manual operation. The valve body is presumed to be made of cast carbon steel or stainless steel and is externally coated in white for protection. Nominal valve bore size is estimated between 10" and 12", based on the flange dimensions. Rotation status is clearly indicated on the actuator with "OPEN / APERTO" and "CLOSE / CHIUDE" labeling for operational safety.

This assembly is ideal for isolating or regulating flow in high-pressure systems where electric or pneumatic actuation is not feasible, and manual control with high mechanical advantage is required.
