DN 15mm~1200mm
ANSI 150LB~2500LB
Strong points:
1. Tight and reliable, ball valve sealing surface material is widely used plastic, sealing good, in the vacuum system has also been widely used.
2. Easy to operate, open and close quickly, from full to full off as long as the rotation of 90 degrees, easy to control long distance.
3. Easy maintenance, ball valve structure is simple, seal ring is generally active, removal and replacement are more convenient.
4. When fully open or fully closed, the sealing surface of the sphere and seat is isolated from the medium, and when the medium passes, it will not cause the erosion of the valve seal ingress.
Ball valve installation and maintenance should pay attention to the following:
1. To keep the position of the valve handle rotation;
2. Cannot be used as a throttle;
3. Ball valves with drive mechanism should be installed upright
Theory:
This type of valve only needs to be rotated 90 degrees of operation and a small torque of torque to close tight. A fully equal valve body cavity provides a direct runner for the medium with little resistance and direct passage. It is generally considered that the ball valve is most suitable for direct open and closed use, the development has been designed to make the ball valve with throttle and control flow. The main features of the ball valve are its compact, easy to operate and service, suitable for general working media such as water, solvents, acids and natural gas, but also suitable for harsh operating conditions such as oxygen, hydrogen peroxide, methane and ethylene.
The ball valve body can be whole or combined.
