Butterfly Valves Manufacturers

A butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

Actuated | AWWA

Actuated Butterfly Control Valves, control the flow of gas or liquid by means of a disk, which turns on a diametrical axis inside a pipe or by two semicircular plates hinged on a common spindle, which permits flow in only one direction. These valves offer a rotary stem movement of 90 degrees or less, in a compact design. Unlike ball valves, they do not have any pockets in which fluids may become trapped when the valve is closed. They are quick opening valves that consist of a metal circular disc or vane with its pivot axes at right angles to the direction of flow in the pipe, which when rotated on a shaft, seals against seats in the valve body. They are normally used as throttling valves to control flow.

AWWA Standards are vital guidelines for all facets of the drinking water community. They provide the minimum requirements for design, installation, performance, and manufacturing of products used in the water industry, including pipe, chemicals, storage facilities, valves, and other appurtenances.

From a family of valves called quarter-turn valves, the "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid.

The valve may also be opened incrementally to throttle flow.

There are different kinds, each adapted for different pressures and different usage.
