Insulated ball valve

Product Overview

Insulated ball valve is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport heavy oil, rubber and other high viscosity media that will solidify at room temperature.

Structural characteristics

1. The flow resistance is small, and its resistance coefficient is equal to that of the same length of pipe;
2. It has the advantages of simple structure, small volume and light weight;
3. At present, the sealing surface material of ball valve is widely used in plastic, which has good sealing performance and is widely used in vacuum system;
4. It is easy to operate and quick to open and close. From full open to full close, only 90 ° rotation is needed, which is convenient for remote control;
5. Maintenance is convenient, ball valve structure is simple, seal ring is generally movable, disassembly and replacement are more convenient;
6. When the valve is fully open or closed, the sealing surface of the ball and valve seat is isolated from the medium, and the medium will not cause the erosion of the valve sealing surface;
7. Wide range of application, diameter from small to a few millimeters, large to several meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, the inlet and outlet should be spherical, so as to cut off the flow.
