Valves - diaphragms

EPDM and EPDM plus diaphragms

Overview

EPDM and EPDM plus diaphragms

Ethylene propylene diene monomer (EPDM) is fairly chemical resistant and offers quality performances in applications with repetitive steam-in-place (SIP) cycles.

We currently have two types of EPDM diaphragm available:

  • EPDM a relatively low cost material widely used in pharmaceutical applications
  • EPDM Plus a Parylene surface treated version which improves the longevity of the EPDM and greatly reduces the stickiness of the diaphragm.

Features and benefits

  • All our diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable
  • Wide temperature range; good in steam applications
  • Not suitable for use with solvents or petroleum agents
  • Parylene surface treated version available
