Overview

Sanitary grade flange lined fluorine diaphragm valve is a type of valve specifically designed for controlling highly clean and corrosive fluids. It is widely used in industries such as pharmaceuticals, food, biotechnology, and semiconductors, ensuring that the medium is pollution-free, leak free, and meets strict hygiene standards (such as GMP, FDA, 3A, etc.).

Product Details

Flange lined fluorine diaphragm valveProduct Structure and Characteristics

(1) Structural composition

valve body: AdoptingStainless steel (304/316L)Material, liningHigh purity fluoroplastics (PTFE, PFA, FEP)Ensure corrosion resistance.
diaphragm：PTFE+EPDM/FKMComposite membrane, corrosion-resistant, high-temperature resistant, and meets food grade requirements.
connection method：

Clamp quick installation type——Compliant with DIN/SMS standards, easy to disassemble and clean quickly.
Threaded——Suitable for small-diameter pipelines.
焊接式（Welded）——Suitable for ultra clean systems (such as the semiconductor industry).

Drive TypeManual (handwheel/handle), pneumatic (ISO 5211 standard), electric (IP65 protection).

（2）Flange lined fluorine diaphragm valveCore Features

Smooth flow channel, avoiding medium residue, in compliance with CIP/SIP (online cleaning/sterilization) requirements.

Diaphragm isolation medium and valve stem eliminate the risk of cross contamination.
Fluoroplastic lining can withstand corrosive media such as acids, alkalis, and organic solvents.
Material byFDA、EC1935、EU 10/2011Certification, applicable to food and pharmaceutical grade applications.

Clamp style design facilitates quick replacement of diaphragms or cleaning of valve chambers.
