Three piece butt welding ball valve

Application:

Three piece ball valves are widely used in the system control of chemical, petroleum, light textile, electric power, food, pharmaceutical, refrigeration and papermaking industries.

The connection form is also butt welding, socket welding (SW), thread; And can be equipped with international standard ISO support platform and locking device. A 90 ° switch positioning mechanism can be set and locked as required to prevent misoperation. The ball valve is a rotary valve with a 90 ° angle, with excellent sealing performance, (full diameter ball valve) large flow coefficient, small flow resistance coefficient, simple structure, long service life and easy maintenance.

characteristic:

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

2. simple structure, small volume and light weight.

3. it is tight and reliable. The sealing surface of the ball valve is widely made of plastic with good sealing performance. It has also been widely used in the vacuum system.

4. it is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close for remote control.

5. the maintenance is convenient, the ball valve structure is simple, the sealing ring is generally movable, and it is convenient to disassemble and replace.

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