Effortless operation: The medium pressure generates a force on the ball and transfers it all to the upper and lower bearings. The ball does not move relative to its position, and the sealing force on the valve seats at both ends is uniform, resulting in low operating torque The movable metal valve seat structure with pre loaded springs is suitable for high temperature, high pressure, and various medium pipelines. According to customer requirements, it can be designed to be suitable for media containing particles, slurries, etc. Widely used in media pipelines such as food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking, etc.
