1. Labor-saving operation: the medium pressure produces force on the ball, and all the force is transmitted to the upper and lower bearings and balls

The body will not move relative to the position, the pressure on the seat seal at both ends is uniform, and the operating torque is low.

2. The movable metal seat structure with spring preload can be applied to high temperature, high pressure and each

kind of media lines.

3. According to customer requirements, it can be designed to be suitable for media containing particles, slurry and so on.

4. Widely used in food, medicine, petroleum, chemical industry, natural gas, steel, environmental protection, papermaking

and other media pipelines.
