Bellow Ball Valve product description

    Bellow Ball 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 Ball Valve的驱动方式为手动,蜗轮传动,气动或电动。Bellow Ball Valve一般采用法兰连接,也可采用对焊连接。波纹管密封球阀通过填料和波纹管的双重作用实现阀杆密封,达到阀门和外界的零泄露。由于波纹管只能承受拉压作用力,只适合于在启闭过程中阀杆作直线升降运动的阀门,所以波纹管阀门一般仅限于截止阀或 gate valve。为使波纹管密封的原理的到更广泛的应用,研制开发了波纹管密封球阀。

Bellow ball valves(General flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from Class150 To Class1500, PN16 To PN100 to cut off or connect the flowing 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/worm gear/pneumatic or electric actuators could be chosen by needs. Double stem sealing structure, i.e. Bellow sealing & packing sealing realizes the zero leakage of valve. As the bellow could only bear tension & compression force, so it could generally suit for valve whose stem is doing linear lifting and down movement during valve's operation, that is Globe valve or Gate valve. In order to widen the applicable area of bellow seals, CHAODA developed the bellow seals ball valve.
