HYDROGEN VALVES

Take On Extreme Conditions

Greene Tweed understands it is necessary to keep fugitive emissions low to stay safe when working with hydrogen – that’s why our solutions are built from the strongest materials for secure hydrogen processing:
  • Avalon® 56 V-stacks made from low permeability, high purity modified PTFE that can reduce leakage at low temperature (-40°C / -40°F) and high pressure (700 bar / 10,152 psi)>
  • Fusion® 938 O-rings made from high performance FKM with exceptional resistance to H2 exposure
  • GT® Ring for extreme pressures (up to 900 bar / 13,050 psi) and RGD resistance
  • MSE® spring energized lip seals for extreme temperatures (from cryogenic to 288°C / 550°F) and pressures (up to 2 070 bar / 30,000 psi)
  • Fusion® 665 O-rings made from high performance FKM for low temperature services (-57°C / -71°F)
  • Arlon® 3000XT cross-linked PEEK with exceptional creep resistance (25x better than PEEK)

HYDROGEN COMPRESSORS

Meet Supply Demands

For the safe transport of hydrogen, Greene Tweed engineers recommend the following compressor solutions:
  • Fusion® 938 O-rings made from high performance FKM with exceptional resistance to H2 exposure
  • GT® Ring for extreme pressures (up to 900 bar / 13,050 psi) and RGD resistance
  • MSE® spring energized lip seals for extreme temperatures (from cryogenic to 288°C / 550°F) and pressures (up to 2 070 bar / 30,000 psi)

  • Xycomp® carbon-fiber reinforced thermoplastic composite with high strength-to-weight ratio
  • Arlon® 4020 PEEK with customized flexible tooth profile to reduce gaps

HYDROGEN INSTRUMENTATION

Durable Metering Solutions

Greene Tweed engineers are aware of the problems caused by exposure to leakage issues when metering hydrogen – that’s why our experts constantly innovate new solutions to keep your instruments durable and safe:
  • Fusion® 938 O-rings made from high performance FKM with exceptional resistance to H2 exposure
  • GT® Ring for extreme pressures (up to 900 bar / 13,050 psi) and RGD resistance
  • MSE® spring energized lip seals for extreme temperatures (from cryogenic to 288°C / 550°F) and pressures (up to 2 070 bar / 30,000 psi)

ELECTROLYSERS AND FUEL CELLS

Drive the Hydrogen Economy

Greene Tweed solutions have been designed to handle the increase in temperatures and pressures required to develop the next generation of fuel cells and electrolysers Arlon® 3000XT:
  • Improved chemical resistance over standard PEEK
  • Retaining mechanical properties of standard PEEK at higher temperature
  • Better resistance to thermal cycling
  • Available as structural rings, cell frames for electrolysers, and compression end plates or MEA sub-gasket films for fuel cells

O-RINGS AND BACK-UP RINGS

When Downtime isn’t an Option

The most common type of elastomer seal, Greene Tweed’s O-rings provide cost-effective, flexible sealing solutions for industry’s harshest conditions. The O-ring can be used either as a seal itself or as the energizing element in PTFE, cap-type seals.

For additional backup rings, Greene Tweed’s engineers will work with you to develop a custom configuration suited to your needs.

T-SEALS

Advanced T-Seals for Demanding Applications

Greene Tweed offers a wide range of standard and custom engineered T-seals for easier assembly, low leakage, and longer service life.

METAL SPRING ENERGIZED (MSE®) SEALS

Versatile Sealing for Demanding Environments

When equipment failure is not an option, Greene Tweed MSE® metal spring energized seals provide superior sealing in even the most volatile conditions:
  • High pressure or low pressure requirements, from vacuum up to 30,000 psi (2,070 bar) plus
  • Large temperature variation, cryogenic to 550°F (288°C)
  • Critical friction requirements
  • Critical wear and life requirements

V-Rings

Versatile Sealing and Scraping for Demanding Environments

For applications requiring specialized elastomeric and/or thermoplastic properties, Greene Tweed’s V-rings, adapters, and seal stacks deliver proven performance when exposed to extreme temperatures, corrosive chemicals, and other damaging contaminants.
