API WCB Floating ball valve

API WCB Floating ball valve

Short Description:

The ball of the floating ball valve is floating, under the action of medium pressure, the ball can produce a certain displacement and tightly pressed on the sealing surface of the outlet section, to ensure the sealing of the outlet end.It can be designed and manufactured according to API 6D/API 608/ BS5351/ASME B16.34.

Advantage

1.Fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length.
2.Simple structure, small volume, light weight.
3.Tight and reliable, ball valve sealing surface material widely used plastic, good sealing, in the vacuum system has been widely used.
4.Easy to operate, quick to open and close, from full open to full close as long as the rotation of 90°, easy to remote control.
5.Easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
6.When fully open or fully closed, the sealing surface of the ball and the seat is isolated from the medium, and the medium will not cause the erosion of the sealing surface of the valve when the medium passes.

Application

The closing part of the ball valve is a ball, the ball rotates around the center line of the valve body to achieve the purpose of opening and closing, the ball valve can not be used to throttle; Ball valves are mainly used to cut, distribute and change the flow of pipeline intermediates. This type of valve should generally be installed horizontally in the pipe. Selection of different materials, can be respectively suitable for water, steam,oil,nitric acid,acetic acid,oxidation medium,urea and other media, can be widely used in papermaking, petrochemical, chemical, metallurgy, electric power, environmental protection, petroleum, light industry and other industrial sectors of the automatic control system.
