KSB heat conduction oil cut-off valve BOA-H using a metal bellows seal manufacturing technology, flexible metal corrugated pipe expansion and high performance, especially the long fatigue life. With bellows seal design, the complete elimination of the general cut-off valve stem packing seal aging fast and easy leakage faults, not only to improve the use of energy efficiency, increase equipment safety, reduce repair costs and frequent repair and maintenance, but also provides a clean and safe working environment.

KSB导热油截止阀BOA-H采用金属波纹管密封技术制造，高性能的弹性金属波纹管，伸缩疲劳寿命特别长。采用波纹管密封的设计，完全消除了普通截止阀阀杆填料密封老化快易泄露的缺点，不但提高了使用能源效率，增加生产设备安全性，减少了维修费用及频繁的维修保养，还提供了清洁安全的工作环境。

The main advantage:

The valve used cone design, sealing surface and the dielectric into a streamlined, better sealing performance, longer service life;

Double seal design (bellows + fill) if the bellows failure, valve stem packing will prevent the leakage, and sealed in line with international standards;

The valve cover is provided with fatliquoring joints, can be directly for the lubrication of the valve rod, nut and sleeve, unlike traditional only for thread lubricating oil;

Ergonomic design of hand wheel, longer service life, easy and convenient operation, higher safety and reliability;

Bellows globe valve, which is the key component of metal corrugated pipe, and the lower end of the stem assembly with automatic roll welding, welding automatic roll and the upper end of the connecting plate, forming a metal barrier between the fluid medium and air, to ensure that the valve stem zero leakage;

KSB导热油截止阀BOA-H主要优点：
KSB导热油截止阀BOA-H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；
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；
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；
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；
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；
