Electric 2PC threaded ball valve

Thread ball valve (ball valve) is a ball, the ball around the center line of the valve body for rotation to open, close a valve.

Ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valve, three-piece ball valve, is a new type of valve widely used in recent years, the valve is generally installed horizontally. Thread ball valve is a kind of ball valve, and the connection form of pipeline is thread connection, there are flange ball valve, welding ball valve and so on.

Applicable place:

Mainly used in nominal pressure PN 16~140, nominal size DN 8~50 low pressure, small diameter pipeline, used to cut off water flow and change the distribution of water flow or used for fast opening and closing places.

Main features:

1) Small flow resistance;

2) Simple structure;

3) Small size and light weight;

4) the sealing surface material of ball valve is made of plastic, with good sealing performance;

5) Easy to operate, quick to open and close, convenient for remote control;

6) Convenient maintenance, sealing ring is generally active, convenient disassembly and replacement;

7) when fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium, and the medium will not cause erosion of the sealing surface of the valve.

Matters needing attention:

1) Small flow resistance;
