Eccentric Half Ball Valve

Eccentricity of the eccentric half ball valve is a certain dimensional deviation between the centerline of the valve shaft and the centerline of the hemispherical body. The valve seat seal is installed on one side of the valve body flow channel. There are two types of eccentric methods, one is the single eccentric structure, and another is double eccentric structure. The single eccentric half ball valve is a valve shaft centerline that is radially offset by a certain size from the centerline of the hemispherical body in the valve body flow channel. The double eccentric half ball valve is a size offset between the centerline of the valve shaft and the centerline of the hemispherical valve, in addition to radial eccentricity in the flow channel, along the axial direction of the valve body flow channel.

Design Advantages

The eccentric ball valve adopts a modular design as a whole, with a simple structure, good reliability, and high universality.

The valve stem uses an anti spray structure.

It adopts a reliable dual sealing method. The soft sealing structure has self sealing performance, while the hard sealing structure has elastic compensation performance.

The straight passage and sturdy eccentric crankshaft make it suitable for high flow rates and vibration free.

The eccentric crankshaft can be opened and closed by rotating 90°, with a short opening and closing time.
