2、用聚合物或金属作密封材料，在高温、高压工况具有优良的密封性能。
3、设置填料箱，防止阀门内腔压力异常升高而使阀杆飞出，增置倒密封结构，能确保填料可靠密封。
4、广泛适用于化工、炼油、油气、天然气、钢铁等介质管路。
1. Resistance to sulfide stress cracking: valve contact medium materials are according to the American association of corrosion engineers NACE01-75 standards for choice, and according to the standard to nickel plating on the surface, can satisfy the requirement of curing environment conditions.
2. Sealing material with polymer or metal, excellent sealing performance in high temperature and high pressure condition.
3. Set the stuffing box to prevent the pressure of the inner cavity of the valve to rise and make the stem fly out, adding the backsealing structure to ensure the packing is reliable.
4. Widely applicable to chemical, oil, gas, natural gas, steel and other media pipelines.
