A manual gear operator transfers hand-applied motion through a gear mechanism to the valve stem or shaft. The section shows the transmission elements and housing. This assembly is selected separately from an electric operator or chainwheel. Specify required torque, the valve interface, gear ratio and mounting orientation. Valve operating effort and access at the installation determine the appropriate operator.

Manual valve gear operatorOperation: Manual · Transmission: Gear mechanism · Selection: Match valve torque and interfaceA manual gear operator transfers hand-applied motion through a gear mechanism to the valve stem or shaft. The section shows the transmission elements and housing. This assembly is selected separately from an electric operator or chainwheel. Specify required torque, the valve interface, gear ratio and mounting orientation. Valve operating effort and access at the installation determine the appropriate operator.

Electric valve operatorPower source: Electric motor · Mounting: On the valve stem assembly · Selection: Match valve travel and torqueAn electric operator drives the mechanism of an industrial valve. The shown assembly mounts the motor and motion-transmission unit above the valve stem, providing powered operation in place of direct handwheel operation. Required torque, travel or number of turns, electrical supply, environmental protection and control signals must match the valve and installation. These are selection requirements, not fixed ratings shared by every operator.

Valve chainwheel operatorOperation: Manual chainwheel · Application: Operation from below · Transmission: ChainA chainwheel allows manual valve operation from a position below or away from the handwheel. The illustrated chainwheel couples to the valve operating mechanism so that hand-applied motion is transmitted through a chain. Specify the installation height, chain reach and mechanical compatibility with the valve. This arrangement is intended to improve access to valves mounted at elevated locations.

Remote floor-stand valve driveAssembly: Mechanical operation transmission · Operating position: Floor stand · Main elements: Connecting shaft / Gear operatorThis assembly transmits manual operation from a floor stand to a remotely mounted valve. A connecting shaft and gear operator link the stand to the valve, separating the operating position from the process body. Determine the distance, mounting orientation, shaft supports and torque requirement for the actual installation. The product is a mechanical remote-drive assembly rather than the isolation valve itself.
