(DIN)进口德标截止阀性能描述 Performance description

(DIN)德标钢制截止阀阀瓣采用锥形设计，密封面与介质成流线形，密封性能更好 RETZ (DIN) German standard steel globe valve clack adopts conical design, and the sealing surface is linear with the medium, with better sealing performance

阀杆调质及表面氮化处理，有良好的抗腐和抗摩擦性能 The valve rod is quenched and tempered and the surface is nitrided, with good corrosion resistance and friction resistance

阀体与阀盖采用覆膜砂制造工艺，填补了传统铸造工艺易泄漏、高污染的弊端，确保阀门无泄漏 The valve body and bonnet are made of coated sand, which fills in the shortcomings of traditional casting technology, such as easy leakage and high pollution, and ensures no leakage of the valve
