Top Entry Eccentric Half Ball Valve Semi Spherical Valve Cast Iron Stainless Steel

Product Overview:

An Eccentric Half Ball Valve is a relatively new type of ball valve, which has some unique advantages related to the structure, including opening and closing without friction, sealing not being worn easily, and small opening and closing torque. This can reduce the size of the actuator and a multi-turn electric actuator can be equipped, which can achieve the purpose of the adjustment and close cutting off of the medium. An Eccentric Half Ball Valve is widely applied to working conditions that require strict cutting off, such as petroleum, chemical, urban water supply and drainage.

Product Characteristics:

1. The eccentric semi spherical valve has a top-mounted structure. The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce costs.
2. The eccentric semi spherical valve has a single seat, which can eliminate the problem that the medium in the valve cavity affects the safe use due to an abnormal pressure increase.
3. The eccentric semi spherical valve has low torque. The valve stem with special structure design can be easily opened and closed only by a small handle.
4. When the eccentric semi-ball valve is opened or closed, there is no friction. This function completely solves the problem of affecting the sealing due to mutual friction between the sealing surfaces for traditional valves.
5. The top entry ball valve has wedge-shaped sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing performance of the valve is not affected by the differential pressure of the pipeline. The sealing performance is reliably guaranteed under various working conditions.
6. The top entry ball valve has self-cleaning structure of the sealing surface. When the ball is tilted from the valve seat, the fluid in the pipeline passes through 360° along the sealing surface of the ball, which not only eliminates the partial scouring of the valve seat by the high-speed fluid, but also removes the accumulation on the sealing surface to achieve the purpose of self-cleaning.
