Bellow Globe Valve product description

    Bellow Globe Valve适用于Class150~Class1500,PN16~PN100的各种管路上,用于截断或接通管路中的介质,选用不同的材质,可分别适用于水,蒸汽,油品,硝酸,醋酸,氧化性介质,尿素等多种介质。Bellow Globe Valve的驱动方式为手动,蜗轮传动,气动或电动。Bellow Globe Valve一般采用法兰连接,也可采用对焊连接。

Bellow seals Globe valves(Generally flanged connection, and Butt-weld ends optional) are suitable for using on various kinds of pipeline from Class150 To Class1500, PN16 To PN100 to cut off or connect the following of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/bevel gear/pneumatic or electric actuators could be chosen by needs. 

    Bellow Globe Valve内部采用波纹管结构,不锈钢的波纹管下端焊接在阀杆上,以防止工艺流体浸蚀阀杆。另一端置于阀体和阀盖之间构成静密封。采用双重的密封设计若波纹管失效阀杆填料也会避免泄漏,波纹管焊于阀杆保持稳定的运行性能,避免由于阀塞振动引起阀杆振动。最适用于蒸汽,易燃,易爆,导热油,高纯度,有毒等介质的管路上。

Bellow sealed structure is used for Bellow globe valve. One end of the stainless steel bellow is welded onto the valve stem to prevent the erossion caused by medium, and the other end is laid between the body & bonnet which forms the static sealing. Double stem sealing (bellow & packing) could ensure the sealing even when bellow doesn't work. Bellow welded onto the stem could ensure the steady performance of valve by avoiding the potential vibration of stem caused by disc. And the bellow seals globe valve is very suitable for pipeline carrying medium of steam, heat conducting oil or others with features of inflammable & exposive, high purity, toxic and etc. 

    波纹管密封截止阀是采用国外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;完全消除了普通阀门阀杆填料密封老化快易泄露的缺点,Bellow Globe Valve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。波纹管密封截止阀适用于石油,化工,制药,化肥,电力等行业的各种工况管路上,用于切断或接通管路介质。

Bellow seals globe valve is designed according to the advanced international metal bellow sealing technology with high performance bellow which has a long life span of fatigue and this type of globe valve could totally eliminate the easy-ageing defect of normal stem packing sealing and causing leakage.  The bellow seals globe valve could not only improve the using efficiency of energy, the safety of production equipment, reduce the cost of maintenance, but also provide a clean & safe working condition. Bellow seals globe valve is suitable for cutting off or connecting the medium of pipeline in industries of petroleum, chemical, fertilizer, pharmacy, power plant and etc. 

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products。CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent。
