Fixed Ball Valve

Product description：

Fixed ball valve with a floating seat, pressure by the media, the valve seat to move, so that the sealing ring tightly pressed on the sphere, to ensure sealing. Usually with the ball in the upper and lower shaft with bearings, operating torque, suitable for high pressure and large diameter of the valve. To reduce the operating torque of the ball valve and increase the reliability of the seal.

Characteristic：

• The utility model has the advantages of simple structure, small size and light weight.
• The fluid resistance is small, and the coefficient of drag is equal to the pipe length of the same length.
• Convenient operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
• Easy maintenance, ball valve structure is simple, the sealing ring is generally movable, disassembly and replacement are more convenient.
• In full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, will not cause the valve sealing surface erosion.
• Tight and reliable, at present, the ball valve sealing surface materials widely used in plastic, good sealing, vacuum systems have been widely used.
• Wide range of applications, from a few millimeters to a few millimeters, large to a few meters, from high vacuum, high pressure can be applied. When the ball rotates 90 degrees, the spherical surface should be presented at the inlet and outlet so as to cut off the flow.
