 Use of the product 

 It is suitable for long pipelines and general industrial pipelines. Its strength, resistance to harsh environments, etc. are considered in the design, and it is suitable for corrosive and non-corrosive media. Compared with the floating ball valve, when working, the force generated by the fluid pressure in front of the valve on the sphere is transmitted to the bearing, which will not make the ball move to the valve seat. Therefore, the valve seat deformation is small, the sealing performance is stable, and it is suitable for high-pressure and large-caliber occasions. The spring pre-valve seat assembly has self-tightening characteristics to achieve upstream sealing. 

 Each valve has two valve seats, and each direction can be sealed, so there is no flow limit for installation, which is two-way. This valve has two-block and three-piece valve body structures. The middle flange is bolted, and the seal is sealed with reinforced polytetrafluoroethylene embedded in the stainless steel ring. The back of the steel ring is equipped with a spring to make the valve seat close to the sphere, which is in line with the seal. 

 The upper and lower stems are equipped with PTFE bearings to reduce friction and save effort. There is no adjustment plate at the bottom of the small shaft, so that the ball and the sealing ring are connected. The full-diameter structure is adopted to make the valve flow hole consistent with the inner diameter of the pipeline, so that the pipeline can be cleaned.
