JY41W不锈钢氧气截止阀采用材质优良的硅黄铜或不锈钢铸造而成，具有机械强度高，耐磨损、安全性好等优点。使用在氧气管路上，具有**的防爆阻燃性能，消除了氧气管路上的不安全因素。   
氧气截止阀属于强制密封式阀门，所以在阀门关闭时，必须向阀瓣施加压力，以强制密封面不泄漏。当介质由阀瓣下方进入阀六时，操作力所需要克服的阻力，是阀杆和填料的磨擦力与由介质的压力所产生的推力，关阀门的力比开阀门的力大，所以阀杆的直径要大，否则会发生阀杆顶弯的故障。近年来，从自密封的阀门出现后，法兰截止阀的介质流向就改由阀瓣上方进入阀腔，这时在介质压力作用下，关阀门的力小，而开阀门的力大，阀杆的直径可以相应地减少。同时，在介质作用下，这种形式的阀门也较严密。我国阀门“三化给”曾规定，截止阀的流向，一律采用自上而下。
