Function Of Sanitary Diaphragm Valve Diaphragm

The most important part of the valve is the performance of the diaphragm, which is directly related to the performance and quality of the entire diaphragm valve.

Sanitary Diaphragm Valve is a high-standard diaphragm sheet used internationally on sanitary diaphragm valves. It is the most reliable product that meets the production process of frequent SIP sterilization; it is widely used in blood products, vaccines, biopharmaceuticals, large and small volume injections, aseptic production, fermentation, injection water supply and distribution circuits. The EPDM support sheet of the double-layer diaphragm sheet not only protects the PTFE in contact with the product, but also enhances the sealing effect of PTFE. The PTFE diaphragm sheet is used together with the EPDM support sheet to achieve the best reliability and service life.

EPDM (ethylene propylene diene monomer rubber) has excellent resistance to water, acids, carbon, salt solutions, phospholipids, acetone and ethanol, in addition, it is also resistant to ozone and steam. Its indicators are as follows:
1 Implementation standard: FDA21 CFR177.2600;

2 Working temperature: -20℃-+130℃;

3 Working pressure: Max 0.6MPA (6BAR);

4 Design life: >300,000 times/25℃;

5 Diaphragm specifications: DN8-DN80.

The diaphragm of the sanitary diaphragm valve is made of a new EPDM polymer with a modified EPDM rubber. It uses high-strength woven materials to ensure maximum strength and durability. The latest vulcanization technology is used to increase the service life and bending times when used for steam.
