J41F4, J41F46 fluorine-lined cut-off valve,Fluorine-lined globe valve,Stop off valve

Product Overview

J41F4-16, J41F46-16 fluorine valve is suitable for -50~150℃ of various concentrations of water, flow acid, hydrochloric acid, hydrofluoric acid and all kinds of organic acids, strong acids, strong oxidizing agents, also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use.

How it works

The outer shell of J41F46 fluorine lining globe valve adopts investment precision casting, high strength, smooth appearance, and liquid contact cavity, valve body, valve cover, valve disc, etc. (chemical medium flow parts) components are selected excellent corrosion resistant materials (fluorine plastic) as lining or coating materials, the use of molded lining molding technology to make the valve has the characteristics of both metal strength and corrosion resistance. The valve seat adopts integral polymer as sealing material, which has excellent sealing performance in a wide range of temperature and pressure; The opening and closing part (valve disc) is driven by the valve stem and moves along the center axis of the valve seat. The valve is mainly used to connect or cut off the medium in the pipeline, but it can not be used to throttle.

Features of structure

1. The disc and stem are designed as an integrated structure to prevent the possibility of internal parts rushing out of the valve body due to the pressure fluctuation in the pipeline. The structure is compact and the use is safe.

2, to ensure that the pipeline medium is absolutely not in direct contact with the valve shell material, excellent corrosion resistance, is an ideal valve for chemical, pharmaceutical, electronic, environmental protection, petrochemical, crude oil and natural gas transmission of corrosive liquid pipelines;

3, with a compact structure, flexible opening and closing, strong corrosion resistance, the stroke is generally 70% of the nominal diameter, is widely used in petroleum, chemical and other pipeline systems as a cut-off medium, but the plastic lining of the cut-off valve is strictly prohibited for flow regulation, so as to avoid the high speed medium flow at the orifice erosion damage sealing surface.
