Flange type fluorine lined globe valve

Short Description:

J41f series fluorine lined stop valve adopts fluorine plastic lining technology, the valve body adopts investment casting, with high strength and smooth appearance. All flow passage parts in contact with liquid are fluorine plastic, so it can be used in corrosive pipeline and pipeline work of any concentration for a long time in the range of – 50 �� C ~ 180C. However, it should be emphasized that the flow regulation is strictly forbidden for the stop valve with fluoroplastic lining, so as to avoid the high-speed medium flow erosion at the orifice and damage the sealing surface. Widely used in petroleum, chemical and other corrosive occasions.

Features of flange type fluorine lined globe valve

�

1. J41f series fluorine lined globe valve refers to the valve whose closing part (disc) is driven by the stem and moves up and down along the center axis of the valve seat. It is mainly used to connect or cut off the medium in the pipe, but it can not be used for throttling. It has the characteristics of compact structure, flexible opening and closing, strong corrosion resistance and short stroke.�

2. The disc and stem are designed as an integrated structure to prevent the possibility of the internals from rushing out of the valve body due to the fluctuation of pipeline pressure. The structure is compact and safe.
