进口全通径全焊接球阀，全通径全焊封钢制球阀性能描述 Performance description

全通径全焊接球阀（全通径全焊封钢制球阀）为一体式全焊接球阀，不会有外部泄漏等现象，由于阀座是由PTFE密封环及弹簧构成的，所以对压力和温度的变化适应能力强，在使用范围内不会产生任何泄漏。球体的加工过程有先进的计算机检测仪跟踪检测，以球体的加工精度高。由于阀体材料跟管道材质一样，不会出现应力不均，不会由于地震及车辆经过地面时而产生变形，管道耐老化。密封环本体采用含量20%C(碳素)的PTFE材质，保障完全无泄漏  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
