Metflex Gas

Metflex supplies more than 16 million diaphragms each year around the world.

Metflex is a specialist manufacturer and supplier of bespoke diaphragms to a wide variety of sectors including the gas industry.  Our expertise enables us to supply homogeneous, rubber-to-metal bonded, fabric reinforced and DFT (Dispersed Fibre Technology) diaphragms using injection, compression, transfer, flashless and fabricated techniques.

Diaphragms are a highly specialised product.  Our experts are able to advise you on design and choice of materials to meet increasing requirements and our engineers will ensure the appropriate production process to provide you with a quality product that meets your needs, ensuring long life and stability.

Applications

Typical applications using diaphragms include:

  • Gas meters, regulators and gas pressure controls
  • Valves – pneumatic, control, cylinder, gas and reducing
  • Pumps – vacuum and petrol
  • Compressors
  • Actuators – air and gas
  • Solenoids
  • Beverage dispensers
  • Pneumatic cylinders
  • Pneumatic servo mechanisms
  • Turbochargers
  • Switches
  • Accumulators
  • High and low pressure applications

Gas Meters

We possess almost a century of manufacturing experience in the gas meter diaphragm industry having started life producing leather diaphragms and seals before switching to modern, rubber polymer based products in the 1960s.

Diaphragm gas meters are the most common type of gas meter, regularly seen in residential and small industrial properties.  We offer DFT (Dispersed Fibre Technology) diaphragms as well as fabric reinforced rubber diaphragms and can supply a wide range of approved materials including those with EN549 & EN13787 approvals.

Please note that we do not stock pre-made products and cannot offer one-off purchases of existing gas meter or regulator diaphragms.

Gas Regulators

Metflex also supplies rubber mouldings into the regulator market. Pressure regulators control the flow of gas at certain pressures, thus protecting downstream equipment from a higher pressured gas than is recommended. Gas pressure regulators regulate pressure rather than flow and therefore our diaphragms are commonly found in the loading and measuring elements of gas regulators.

Metflex gas regulator diaphragms can be homogeneous (no reinforcement), fabric reinforced, incorporate metal inserts or even made using our range Dispersed Fibre Technology rubbers.

Please note that we do not stock pre-made products and cannot offer one-off purchases of existing gas meter or regulator diaphragms.

Material Selection

Elastomer components can be critical to the operation and safety of equipment.  Therefore, choosing the correct elastomer for your application demands consideration to the following:

  • The material(s) which the elastomer may come into contact with over its lifetime of use, for example fluids, oils or chemicals
  • Ozone resistance
  • Operating temperatures

By the suitable choice of ingredients, the upper and lower operating temperatures can be extended to match your needs.  When developing any component, the following will be considered:

  • Hardness – normally quoted in IRHD or Shore A as tolerance or a range, usually within +/- 5 degrees of hardness
  • Tensile strength
  • Elongation at break
  • Resistance to compression
  • Tear strength
  • Flexibility resistance
  • Abrasion resistance
  • Burst pressure testing
  • Chemical resistance

Material Design

Metflex designs and compounds its own elastomer materials in our fully equipped development laboratory.  All materials compounded in our factory mill room are quality checked and approved prior to the manufacturing process.  Compression, transfer and injection moulding, as well as the preparation of metals and fabrics, are just some of our manufacturing capabilities.

Laboratory facilities

  • Hardness testing – IRHD, shore A and micro
  • Computerised rheometer (MDR) for cure testing of compounds
  • Mooney viscometer for the measurement of rubber viscosity at certain temperatures
  • Tensometer for the measurement of tensile, modulus and elongation at break
  • Compression set equipment
  • Environmental cabinet
  • Cell ageing ovens and general purpose oven
  • Gehman low temperature testing
  • Flex testing for coated fabrics
