The slurry specific hemispherical valve system is a new type of product developed and researched by our company through the introduction of advanced foreign technology. This series of products is mainly used for conveying media that are prone to sedimentation, scaling, crystallization, and contain impurities. The structure adopts the eccentric wedge principle and achieves the functions of locking, adjusting, and opening and closing through the transmission mechanism. There are two types of spherical structures: ordinary hemisphere and V-shaped hemisphere. Among them, the hemisphere valve with V-shaped incision not only has the function of ordinary hemisphere valve, but also adds unique adjustment function. This series of products has a novel structure, stable performance, fast and lightweight opening, self compensating for wear and tear: the seal is reliable and durable, and different sealing materials can be selected according to different working conditions, and it is easy to adjust and maintain; It can self remove scaling, facilitate valve opening, and has no "dead zone", overcoming the disadvantages of ordinary valves such as easy scarring, blockage, leakage, and short service life.

The driving devices include manual, worm gear transmission, pneumatic, and electric.

Note: The size of the series connecting flange can be designed and manufactured according to user requirements

Paper making, pharmaceuticals, dye chemicals, alumina slurry, etc.

1. The movable valve seat structure with leaf spring loading ensures that there is no jamming or detachment between the valve seat and the ball core, providing reliable sealing and a long service life.
2. The V-shaped cut between the ball core and the metal valve seat has a cutting effect, especially suitable for materials containing fibers, small solid particles, slurry, etc.
3. When fully open, the flow capacity is large, the pressure loss is small, and the medium will not deposit in the cavity of the valve body.
4. The structure is novel, compact, and highly versatile. The pneumatic V-shaped cut-off ball valve also has the function of precise adjustment and reliable positioning, with flow characteristics of approximately equal percentages, a large adjustable range, and a maximum adjustable ratio of 100:1.
