Three piece flange ball valve and gate valve are belong to the same type of valve, the difference in its closure is a sphere, the sphere around the center line of the body to achieve the opening and closing of a valve. Ball valve in the pipeline is mainly used to do the cutting, distribution and change the direction of the flow of media. Three piece ball valve is widely used in recent years, a new type of valve.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.

Matters needing attention
1 to stay with the position of the valve handle rotation.
2 cannot be used as a throttle.
3 with the transmission of the valve should be installed upright.
Three piece flange ball valve works by rotating the valve to make the valve flow or occlusion. Valve switch light, small size, can be made large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, widely used in various industries.
Advantage：
1 fluid resistance is small, and its resistance coefficient is equal to that of the same length.
2 simple structure, small size, light weight.
3 close and reliable, ball valve sealing surface material widely used plastic, good sealing, in the vacuum system has also been widely used.
4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5 maintenance convenient, simple structure, the sealing ring is generally active, demolition and replacement are more convenient.
6 in the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the media through, will not cause the valve sealing surface erosion.
7 wide range of applications, from small to a few millimeters diameter, large to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, the inlet and outlet of the ball should be all of the spherical surface, thus cutting off the flow.
Three piece flange ball valve is a relatively new type of ball valve, it has its own unique structure of some of the advantages, such as the switch without friction, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuator. Equipped with multi turn electric actuator, can realize the adjustment of the medium and tight cut off. Widely applicable to the city water supply and drainage of the oil and water supply and drainage and so on.
