Advantages Of Eccentric Half Ball Valve

  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.

  The advantages of eccentric half ball valve are simple structure, easy operation, easy maintenance, tight and reliable, fast opening and closing, etc., as follows:

  1. The structure is simple: the eccentric half ball valve is composed of the valve body and the hemisphere, which is simpler than the gate valve. Small size and light weight.

  2. Easy to operate: open and close quickly, from full open to full close as long as the rotation 90 degrees, easy to remote control, compared with the gate valve switching time is shorter, the failure rate is lower.

  3. Easy maintenance: ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient, compared with the gate valve maintenance is often shorter, less maintenance labor.

  4. Tight and reliable: the sealing surface material of the eccentric half ball valve is widely used in plastic, rubber, etc., which has better sealing effect

  5. Fast opening and closing: full open to full close only need to turn 90 degrees, very easy to compare the remote switch control. The valve body cavity does not cause the medium deposition caking, overcoming the gate valve, stop valve and other easy blockage, easy leakage, short life and other drawbacks, showing its unique superior performance, to maintain the normal opening and closing of the valve and regulating function.

  6. The fluid resistance is small, and the resistance coefficient is equal to the pipe segment of the same length. Large circulation capacity and small pressure loss when fully open.

  7. 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.
