PTFE PFA Lined Pneumatic Diaphragm Valve for Fluorine Chemical
YFM lined diaphragm valve adopt special technology by lined PFA/FEP on body, diaphragm is made of PFA/FEP and EPDM thus all wetted parts are reach same performance of corrosion resistance. This valve has good at throttles with advantage of corrosion resistance and abrasion resistance, reliable sealing performance and widely used in corrosive medium, fiber, powder etc.
Product Feature:
Less parts and good performance
Fast throttle
Open limitation conveniently, flexibly, precisely
Fine body structure for easy assembly and maintenance.
All wetted parts are lined by fluorine, totally isolate from medium to avoid any corrosion on body.

On pressure and vacuum, YFM diaphragm valves operate and close 100% leaktight even after thousands of operations. This feature reduces
processing and handling costs, by eliminating emissions normally associated with conventional valve designs.
All working parts of the valves are isolated from the line media and positive closure is obtained even on frequent cycling or with entrained
particulates in the line unlike quarter turn ball and butterfly valves. Throttling and control characteristics are enhanced by a streamlined flow path
that is cavity free and provides excellent flow control capabilities.Extended life, reliability, safety and ease of use, combined with an essentially
simple design, results in low maintenance for minimum running cost.
