Introduction

Flange ball valve is mainly used to cut off, distribution and change the flow direction of the medium.

Features

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

2. Simple structure, small size and light weight.

3. Tight and reliable, the sealing surface material of ball valve is widely used in plastic, with good sealing performance, and it has been widely used in vacuum system.

4. Easy to operate, fast to open and close, from full open to full close as long as the rotation of 90°, easy to remote control.

5. Convenient maintenance, simple structure of ball valve, sealing ring is generally mobile, easy to remove and replace.
