适用于工作温度-29～425℃（碳钢）及-40～500℃（不锈钢）的各种管路上，用于截断或接通管路中的介质。
通过选用不同的材质，可适用于水、蒸汽、油品、硝酸、醋酸、强氧化性介质及尿素等多种介质。
直流通道设计，管壁平洁光滑，使流体介质经过管壁时产生的阻力极小，摩擦系数小，输送效率高
标准法兰连接，耐压性好，具有较好的密封性，可采用各种配管法兰标准及法兰密封面形式，满足各种工程需要及用户要求
阀瓣采用双闸板中间带万向顶结构，能自动调整阀瓣与阀座密封面吻合度，保证阀门的密封，同时此结构维修方便，阀瓣互换性较好
阀杆经调质及表面氮化处理，有良好的抗腐蚀性、抗擦伤性和耐磨性
采用楔式弹性闸板结构，中大口径设置推力轴承，磨擦力小，并配有撞击手动，启闭轻松自如
密封副配对先进合理，闸板和阀座的密封面采用不同硬度的司太立钴基硬质合金堆焊而成，密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长
