A Chain Pulley Butterfly Valve is a type of butterfly valve that is operated using a chain and pulley mechanism. These valves are used to regulate flow within a piping system. In the case of a Chain Pulley Butterfly Valve, instead of directly turning a handle or lever, a chain and pulley system is employed for operation.
They are named “butterfly” because of the metal disc (the “butterfly”) positioned in the center of the valve that rotates on a shaft to control the flow of fluid. This system allows for remote operation of the valve, which can be useful in situations where the valve is located in a hard-to-reach or hazardous area.
The chain and pulley mechanism typically works by attaching one end of the chain to the valve's shaft and running the chain through a series of pulleys. By pulling or releasing the chain, the valve can be opened or closed as desired. This type of valve operation is often found in industrial applications where manual operation may be impractical or unsafe.
