主要优点：
1、波纹管截止阀，其关键部件金属波纹管，下端与阀杆组件采用自动滚焊焊接，上端与连接板自动滚焊接，在流体介质和大气之间形成一个金属屏障，确保阀杆零泄漏；
2、阀瓣采用锥形设计，密封面与介质成流线形，密封性能更好，使用寿命更长；
3、双重的密封设计（波纹管+填料）若波纹管失效，阀杆填料也会避免泄漏，并符合国际密封标准；
4、阀盖上自带有加脂接头，可直接对阀杆、螺母和轴套进行润滑，不像传统的只对螺纹加润滑油；
5、人体工程学设计手轮，使用寿命更长，操作轻松便捷，更安全可靠；
The main advantages:
1, bellows globe valves, the key components of metal bellows, the lower end of the stem assembly automatic roll welding, automatic roll welding the upper end of the connecting plate between the fluid medium and atmosphere to form a metal barrier, ensuring zero stem leakage ;
2, the valve design tapered sealing surface and media into a streamlined, better sealing performance, longer life;
3, dual seal design (bellows + filler) if bellows failure, stem packing will avoid leakage and comply with international standards sealed;
4, valve cover comes with grease fittings, can be directly stem, nut and sleeve for lubrication, unlike traditional only lubricate the thread;
5, ergonomic hand wheel, longer life, easy operation and convenient, more secure and reliable;
