Eccentric ball valve

Nominal pressure:PN0.25~4.0MPa
Nominal diameter:DN50~600mm

Eccentric half ball valve is a relatively new type of ball valve category, it has its own structure has some unique advantages, such as no friction switch, seal is not easy to wear, small opening and closing torque. This reduces the size of the configured actuator. With a multi-turn electric actuator, the medium can be adjusted and tightly cut off. It is widely used in petroleum, chemical industry, urban water supply and drainage and other conditions requiring strict cut-off.

1, eccentric half ball valve opening and closing without friction, this function completely solves the traditional ball valve due to friction between the sealing surface and affect the sealing problem.

2, designed for the top structure, the valve installed on the pipeline can be directly online inspection and maintenance, can effectively reduce the device parking, reduce costs.

3. When the eccentric half ball valve is fully opened or fully closed, the sealing surface of the ball and the seat is isolated from the medium. When the medium passes, the sealing surface of the ball valve will not be eroded.

4, low torque design, special structural design of the stem, just with a small hand ball valve can be easily opened and closed.

5, eccentric half ball valve sealing surface structure has self-cleaning function. 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.
