Product introduction Fully welded ball valve, there will be no external leakage. The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high. Since the valve body material is the same as the pipe material, there will be no uneven stress, no deformation due to earthquakes and vehicles passing the ground, and the pipe is resistant to aging. The body of the seal ring is made of RPTFE with a content of 25% Carbon, which guarantees no leakage (0%). Product Features 1. The valve body is welded by steel pipes. 2. The ball pad is made of reinforced polytetrafluoroethylene. 3. The valve stem adopts explosion-proof design. 4. Temperature range: -60-200℃ 5. Drive mode: manual or turbine drive. 6. Testing standard: Api598. Application field City gas: gas output pipeline, main line and various branch supply pipelines, etc. Centralized heating: output pipelines, main lines, and branch lines of large heating equipment. Heat exchanger: the pipeline and each circuit are opened and closed. Steel plants: various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines.
