KEOFITT offers PTFE, silicone and EPDM diaphragms, providing optimal flexibility and durability for various applications.

PTFE is chemically inert and resists corrosion, ensuring cleanliness and safety when transporting sensitive liquids. 

Silicone offers high temperature resistance and flexibility, making it ideal for hygienic environments where sterility is essential.
 
EPDM is durable and has good resistance to ozone and UV light, contributing to long-term safety in external environments. 

These membranes minimize the risk of contamination and ensure that products retain their quality and integrity.

Diaphragms are supplied fitted to the selected valve head and are easily replaced as spare parts.
