Fluorine lined bellows control valve is bellows sealed globe control valve complying with emission standard ISO15848 & TA-LUFT. All wetted parts are fluorine lining. The lining is nested on the valve body, which is firm and not easy to fall off. It can withstand certain negative pressure and can be used for gas medium with low fugitive packing. The valve is usually fluorine lined. In order to adapt to high pressure conditions it also can use Hastelloy C as bellows material.
It is used for the regulation and control of corrosive, harmful, pure and small amount of solid media in chemical, pharmaceutical and other industries.
