PVC Butterfly Valve

PVC Butterfly Valve

Butterfly Valves are used in applications to isolate or regulate flow and its operation is similar to a ball valve to allow for quick shut off. A butterfly valve is often chosen because of its lower cost and lighter weight. Butterfly valves are made up of four main components, a body, disk, stem and seat. A disk performs the closing mechanism on the valve and is positioned in the center of the pipe with a rod passing through it is connected to the actuator on the outside of the valve. The actuator can be rotated to turn the disc to be either parallel or perpendicular to the flow, so a drop in pressure can be avoided. Butterfly Valves are available in actuated or manual versions, and different types of butterfly valves are available to adapt to different levels of pressure and usage levels.
