Pneumatic three-way ball valve-Ball valve series-

Product description

Pneumatic three-way ball valve is a three-channel rotary ball valve, which is used for medium diversion, confluence and flow direction switching. Any pipe can be used as an inlet or outlet. There are two types of pneumatic three-way L-type ball valve and pneumatic three-way T-type ball valve, which can meet different industrial requirements. The three-way L-type ball valve cuts off two of the three pipelines, and the three-way T-type ball valve realizes the confluence and diversion of the three connecting pipelines. Widely used in chemical industry, petroleum, light textile, electric power, food and pharmaceutical, refrigeration and paper making and other fields.

Product Features

1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.

2. Simple structure, small size and light weight.

3. Tight and reliable, at present, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum systems.

4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. Easy maintenance, simple structure of ball valve, sealing ring is generally active, disassembly and replacement are more convenient.

6. When fully open or closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause the erosion of the sealing surface of the ball valve.
