進口全通徑全焊接球閥，全通徑全焊封鋼制球閥性能描述 Performance description

全通徑全焊接球閥（全通徑全焊封鋼制球閥）為一體式全焊接球閥，不會有外部泄漏等現象，由于閥座是由PTFE密封環及彈簧構成的，所以對壓力和溫度的變化適應能力強，在使用范圍內不會產生任何泄漏。球體的加工過程有先進的計算機檢測儀跟蹤檢測，以球體的加工精度高。由于閥體材料跟管道材質一樣，不會出現應力不均，不會由于地震及車輛經過地面時而產生變形，管道耐老化。密封環本體采用含量20%C(碳素)的PTFE材質，保障完全無泄漏  RETZ  Full bore full welded ball valve (full bore full welded sealed steel ball valve) is an integral full welded ball valve without external leakage. Since the valve seat is composed of PTFE seal ring and spring, it has strong adaptability to changes in pressure and temperature, and will not produce any leakage within the scope of use. The machining process of the sphere is tracked and detected by an advanced computer detector, and the machining accuracy of the sphere is high. As the valve body material is the same as the pipe material, there will be no uneven stress, no deformation due to earthquake and vehicles passing the ground, and the pipe is aging resistant. The seal ring body is made of PTFE with a content of 20% C (carbon) to ensure no leakage
