Fixed

Fixed ball valve

Nominal pressure:PN1.6~6.4MPa
Nominal diameter:DN15~100mm

1. Frictionless opening and closing. This function completely solves the problem that the sealing of traditional valves is affected by the friction between the sealing surfaces.

2, top type structure. The valve installed on the pipeline can be directly checked and repaired online, which can effectively reduce the device parking and reduce the cost.

3, single seat design. The problem that the medium in the valve cavity is affected by abnormal pressure increase is eliminated.

4, low torque design. The valve stem with special structure design can be easily opened and closed with a small hand handle.

5, wedge sealing structure. The valve is sealed by the mechanical force provided by the valve stem, and the ball wedge is pressed to the seat, so that the sealing of the valve is not affected by the change of the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of sealing surface. When the ball tilts away from the seat, the fluid in the pipeline passes 360° evenly along the sealing surface of the ball, which not only eliminates the local erosion of the high-speed fluid on the seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.




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

2, simple structure, small size, light weight.

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

4, easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.

5, easy maintenance, ball valve structure is simple, the 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 valve sealing surface.

7, wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
