Notes & Highlights

1) Above data is provided as guideline for the selection of material, MASCON carries no responsibility due to non suitability of the same.

2) All our food grade diaphragms are supported with food grade certificate complying with FDA certified raw material.

3) All our diaphragms are manufactured with best quality Nylon re-enforcement, hence are reliable for rated pressure.Systematic curing

and manufacturing process ensures long life of the diaphragms.

4) Our Manual as well as Pneumatic valves are neatly designed to suite pressure And vacuum too.

MASCON offers various types of Diaphragms

These diaphragms are connected to compressors by rotating the stud in to the female treading of compressor.

We offer PTFE laminated with EPDM rubber type one piece diaphragms with screwed type connections.

These diaphragms are used as standard for DN15 to DN80 Pneumatic valves.

We also offer two piece PTFE diaphragms for sizes above DN65 toDN200.
