Elastomer Backed Two Piece TFM™ Diaphragms for Gemü™ Valves

Genuine Newman 2107 EPDM (Ethylene Propylene Diene Monomer)

Genuine Newman 2107 EPDM is the material of choice for many food and biopharma processing applications, surpassing other EPDM’s on the market for decades in performance and reliability. An excellent general purpose elastomer, resistant to many chemicals, polar solvents, many CIP solutions,

and most aqueous-based systems. When used as a backing in two-piece diaphragms, Newman 2107 has been shown to impart outstanding sealing properties at the lowest bonnet torque values, a substantial improvement over OEM parts.

Genuine Dyneon™ TFM™ (Modified PTFE) with Elastomer Backing

Genuine Dyneon™ TFM™ from 3M® when used in conjunction with Newman’s proprietary processing has resulted in the highest chemical resistance and the lowest permeability and makes it ideal for almost all processing conditions where extended service life is desired. It is resistant to almost all chemicals, solvents, and CIP solutions, and has been tested to 500 one-hour steam cycles/100,000 valve cycles in many valve configurations. It is ideal for continuous steam, hot WFI and processing areas. These diaphragms are shipped together with a paired elastomer backing piece made of Newman 2107 EPDM.

  • Temperature Range (with EPDM backing): -20°F (-28°C) to 300°F (148°C).
  • Temperature Range (with Viton® backing): -0°F (-17°C) to 450°F (232°C).

Certificates Available:

  • FDA Extraction Studies per 21CFR177.2600 (elastomers) and 21CFR177.1550 (PTFE)
