DYQ340F Top Entry Eccentric Half Ball Valve

The eccentric hemispherical valve uses an eccentric valve body, an eccentric sphere and a valve seat, and the valve stem is automatically centered on a common trajectory when it rotates, and the tighter the closing process, the tighter the sealing purpose is. The ball and seat of Fuxiameike valve are completely separated, which eliminates the wear of the sealing ring, and overcomes the problem that the traditional ball seat and the sealing surface of the ball are always worn. The non-metal elastic material is embedded in the metal seat, and the metal surface of the valve seat is affected good protection. This product is especially suitable for steel industry, aluminum industry, fiber, tiny solid particles, pulp, coal ash, petroleum gas and other media.

1. Small pressure loss: when fully open, the water loss is zero, the flow channel is completely unobstructed, and the medium will not be deposited in the cavity of the valve body;

2. Resistance to particle wear: There is a shearing effect between the ball crown of the V-shaped opening and the metal valve seat. During the closing process, the ball crown only leans against the valve seat for a moment, no friction is formed, and the valve seat is wear-resistant. Made of nickel alloy, it is not easy to be washed and worn, so it is suitable for fibers, tiny solid particles, pulp, etc.;

3. Suitable for high flow rate medium: straight-through flow channel, solid eccentric-crankshaft makes it suitable for high flow rate without vibration;

4. Long service life: no wearing parts, due to the eccentric effect, there is no friction between the sealing surfaces when the valve is opened and closed, so the service life is long;

5. Convenient maintenance: valve maintenance does not need to be removed from the pipeline, just open the valve cover to carry out maintenance;

6. Widely used in water, sewage, materials containing tiny solid particles, water, steam, gas, natural gas, oil, etc.
