Saunders EX Endurance Diaphragm

The ideal solution for high temperatures

Key features

  • Excellent performance for prolonged exposure of high temperatures
  • Ideal for steam supply, steam distribution, sterile barriers, steam condensate and Block-and-Bleed applications
  • Improved sealing and reduced demand for tension

General Data

Saunders EX diaphragm is a two-part membrane consisting of a modified PTFE front (TFM) and a support membrane in reinforced silicone.

Compared to a standard EPDM diaphragm, the silicone membrane has an exceptional performance at high temperatures without evidence of deterioration of physical properties and deformation. When exposed to high temperatures for a long time, EPDM rubber will lose its flexibility and thus lose the good support for the PTFE front.

The EX diaphragm is tested on continuous steam at 175°C (347°F).

Applications

The EX diaphragm is the ideal solution for applications with high temperatures.
  • Vapor distribution and supply
  • Vapor sterilization
  • Sterile barriers
  • Vapor barrier
  • Process lines exposed to SIP for a longer period of time

Construction
214 / modified PTFE (TFM) front
  • Finish crystalline and amorphous structure vs. Standard PTFE
  • Optimum resistance to deformation during steam sterilization
  • Ideal for steam applications at high temperatures


Silicone support membrane

  • Dicumyl peroxide hardened
  • Excellent thermal properties
  • Fantastic back resilience
  • Enhanced with fabric to optimize flexibility


Dimensions

  • DN008 - 100 (0.25 "- 4")

Identification and labeling

All diaphragms are provided with production date, cure date, diaphragm type, dimension, and Saunders ID, which provides full traceability.

The EX diaphragm is delivered in DN015-100 with bayonet fitting for best performance and easy assembly. DN008 comes with thread.


Approvals

  • FDA 21CFR Part 177
  • USP class VL <87>, <88> (3rd party test)
  • ASME BPE part SG
  • Certified Animal Derived Component Free (ADCF)
  • Full traceability in terms of EN 10204 3.1

Both the TFM front and the silicone support membrane are developed and manufactured by Saunders. Only use original Saunders spare parts to ensure optimum performance, reliability and compliance with applicable regulations and standards.

Aseptic Diaphragm Valve at KLINGER Denmark

KLINGER Denmark offers a wide range of aseptic diaphragm valves. The aseptic diaphragm valve is simple and ingenious, featuring a dead-leg-free and aseptic design that is widely used in the pharmaceutical industry. The valve consists of three main components: the valve body, the diaphragm, and the actuator for opening and closing the valve.

Only the diaphragm and valve body come into contact with the medium. Saunders supplies valves according to all common standards such as ASME BPE, ISO 1127, SMS 3008, DIN 11850, Schedule 10S, and materials compliant with EC1935 and FDA. The Saunders diaphragm valve is self-draining, with a specified drainage angle on the valve body. The diaphragms are developed and manufactured in-house by Saunders and are state-of-the-art in terms of durability and performance. Saunders offers a wide selection of rubber and PTFE diaphragms that cover the applications used in the pharmaceutical industry.

In addition to standard two-way valves, customer-specific multi-port, dead-leg-free block valves are produced for optimal space and functionality. All types can be supplied with pneumatic control and feedback indicators for on/off operation, as well as with positioners for regulation.
