J41B ammonia globe valve has stable sealing performance, safe and reliable use, strong corrosion resistance, no media leakage and lightweight operation, successfully solved the chemical pipeline with ordinary valves poor corrosion resistance, easy to perforate the shell as well as poor sealing performance, easy to leak the problem. Especially suitable for chemical industry ammonia, gas pipeline transmission, and to meet the requirements of long-term reliable use of its sealing, maintainability, safety and so on. Widely used in freezing, refrigeration, chemical, petroleum, food, smelting, liquefied gas and other industries.
Product Features
- 针对普通阀门耐腐蚀性能差、壳体易穿孔的缺点，根据介质具体特性，氨气专用阀在阀体材料上选用耐腐蚀钢（低温碳素钢添加耐蚀合金元素），可耐氨气、液氨腐蚀，低温可至－40℃，最大限度保证工况条件使用要求。
- 氨用截止阀密封副配对结构型式采用球、平面型，密封自动补偿，达到双重保险的效果，密封性能稳定，无粘着磨损，有效地解决了化工管道用普通阀门密封性能差、易泄露的难题。
- The flange incorporates a tongue-and-groove sealing structure, ensuring absolutely reliable sealing even under fluctuating pipeline pressures.
- The upper sealing assembly employs multi-stage PTFE sealing materials to form a composite seal, ensuring no medium leakage from the packing gland throughout the valve's service life. This eliminates the inherent weaknesses of conventional valve packing gland seals—such as susceptibility to leakage and potential accidents—that are prone to occur.
