Labor-saving operation: The medium pressure on the ball generates all the force to the upper and lower bearings, the ball body will not move relative to the position, the sealing force of both ends of the seat is uniform, and the operating torque is low. The spring preloaded movable metal seat structure can be used for high temperature, high pressure and various media pipelines. According to customer requirements, can be designed to be suitable for media containing particles, slurry and so on. Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper and other media pipelines.
