Explanation of how hydraulic butterfly valve work

Hydraulic butterfly valve are a type of quarter-turn valve that is designed to regulate or isolate the flow within a system. The main components of a butterfly valve include a disk connected to a rod, referred to as the “butterfly,” and the valve seat. The operation of these valves involves the rotation of this disc to control the flow of fluid.

When the valve is open, the disc rotates to allow fluid to pass through. To close the valve, the rod rotates the disc, blocking off the passageway. Some butterfly valves also feature a resilient seat that provides a tight shut-off on the circumference when the disc is rotated.

These valves are commonly used in water supply systems due to their simple construction and efficient operation. They are also used for quick shut-off in various piping systems⁵. In addition to starting and stopping the flow, butterfly valves can also restrict the flow within a system, making them useful for repairs, cleaning, or alterations of fluids when no fluid is running through the pipeline.

The handle of a butterfly valve is used to control its position. To open the valve, the handle is turned partway, and to close it, the handle is turned perpendicular to the stem. If the butterfly valve is closed, the lever must be parallel to the stem, and if it’s open, it will be horizontal.

Describing the components of hydraulic butterfly valve including the actuator, disc, stem and seals

Hydraulic butterfly valves are composed of several integral components, each playing a crucial role in its operation.
