What Is The Function Of 3pc Flanged Ball Valve?

3PC Flanged Ball Valve feature an eccentric metal seal structure. Sealing methods include metal-to-metal, interchangeable metal-to-metal, and stainless steel and graphite composite plate seals. In addition to electric actuation, metal-seal butterfly valves can be operated manually, by worm gear, or pneumatically. These valves are generally installed horizontally in the pipeline.

The disc of a metal-seal butterfly valve is installed diametrically within the pipeline. Within the cylindrical passage of the valve body, the disc-shaped disc rotates around its axis within an angle of 0° to 90°. When the disc is rotated to 90°, the valve is fully open.

A metal hard-sealed ball valve is used to improve the gas dissolution efficiency of high-flow liquids. It includes: a valve body, inlet and outlet valve covers, each of which has a flow channel and is arranged on both sides of the valve body of the product; a valve ball, which has an internal channel and is placed in the valve body of the product; a rotating mechanism, which is connected to the valve ball of the product and is used to rotate the valve ball of the product; a driving device, which is used to drive the rotating mechanism of the product; it is characterized in that it also includes: an impeller mechanism, which is placed in the valve ball channel of the product, and the impeller mechanism of the product includes: a variable-pitch spiral impeller, and the pitch of the variable-pitch spiral impeller of the product increases from the liquid inlet valve cover of the product to the liquid outlet valve cover of the product.
