Chain Operated Butterfly Valve is made of stainless steel or carbon steel. The chain drives the worm gearbox so the valve can be operated manually from a suitable accessible location. Confirm the chain route, operating position and clearance for the selected installation.
Frequently Asked Questions
What measurements should I provide for a chain-operated installation?
Provide the valve mounting height, the intended operating position and the available route for the chain. Request confirmation of the required chain arrangement and clearance for the selected gearbox before ordering.
Does chain operation mean this valve needs an electric or pneumatic supply?
The arrangement described on this page uses a chain to operate the worm gearbox. Specify the intended manual operating location and duty; do not assume that an actuator or remote position indication is included.
How do I choose between the listed carbon-steel and stainless-steel versions?
Send the process medium, operating pressure and temperature, external environment and project material requirements. Confirm the body and wetted-component materials for the selected valve rather than choosing from the body material name alone.
