Hydrogen High Flow Solenoid Valve with Integrated Check Valve - HyValve Mosaic - H35 - H70

Eugen Seitz AG

  • Flanged valve connection for H2 applications, e.g. H2 refueling
  • Hydrogen high flow solenoid valve with integrated high-flow check valve
  • Automatic cascading eliminating the need for many meters of stainless steel MP piping and up to several hundred bolting points
  • Valve junction: Complete flexibility in the refueling experience

Hydrogen high flow solenoid valve with integrated check valve - HyValve Mosaic - H35 - H70

  • Design your own HyValve Mosaic:
    • with 2 to 40 solenoid valves in any matrix
    • whether 500 bar or 1000 bar
    • individually removable valves
    • maintenance can be carried out in-situ
    • integrated check valve
    • 2/2-way solenoid valve, NC
  • Pressure range: 10 bar to 1000 bar (145 psi to 14500 psi)
  • Single test valves are available
  • Hydrogen solenoid shut-off valve, piloted with own fluid
  • Every valve tested at 100% with hydrogen gas mixture
  • All wetted materials fully hydrogen compatible, no hydrogen embrittlement
  • High-performance dynamic seals for tightness and long service life

Key features

  • Different MP tubing sizes: 9/16', 3/4', 1'
  • Piping connections to the baseplate of HyValve Mosaic: MP Cone & Thread
  • Kv m3/h | Cv US-gal/min depend on the orifice of the HyValve Mosaic mounted valve
  • Pressure range up to 1000 bar
  • Lifetime 500000 cycles
  • Rated voltage 24V AC/DC or 230V AC
  • Rated power 16W
  • Operating time: 100% continuous duty
  • Relative humidity: max. 95% (non-condensing)
  • IP-Code 65/67 according to EN 60529

Benefits

  • Small: most compact system design with best accessibility
  • Reduced C&T connections: minimized leakage points, e.g. 3x3 -> 6 connection points
  • Maintenance at site: individually removable valves only 5 to 8min needed to exchange HyValve with integrated check valve
  • Easy functionality and leakage via system control
  • Eliminated pneumatic air  (no humid air = no freezing issues)
  • Ease of mind during refueling

Solenoid coil 2F86: Approvals

  • EPS 18 ATEX 1098 X

  • NEPSI GYJ 18.1429 X
  • II 2G Ex mb IIC 150°C(T3) …(T4*) Gb (* T4 up to +65°C ambient)

Application areas

  • Suited for all high-pressure hydrogen applications
  • Hydrogen Refueling Stations (HRS): Cascade storage valve/priority panels and dispensers
  • Trailer and mobile refueling
  • Medium pressure fluid handling systems
  • Test applications

Project cases

  • Hydrogen Refueling Stations (HRS), HyValve Mosaic is used for managing hydrogen gas flow in and between storage banks (cascade), cryo-pump, compressor and dispenser
  • The highest-capacity and fastest-flow refueling stations in the world rely on HyValve performance
  • HyValve Mosaic are actively operating in refueling stations in California, USA
  • HyValve Mosaic are also used as shut-off valves upstream of hydrogen pressure regulators, to enable the downstream pressure regulator to remain gas-tight

Eugen Seitz AG SeitzValve is an independent, family-owned company with more than 60 years of experience. The core business of Eugen Seitz AG is solenoid valve technology for technically demanding applications. We develop solutions for gaseous media at medium to high pressure (16 to 1,000 bar). We are fully vertically integrated: All our products are developed, produced, packaged, and shipped from our head office in Switzerland in Wetzikon near Zurich. Our competitive offering is enabled by a high degree of automation – production runs 24/7 and with minimal manual input. Our industry-leading valves for hydrogen refueling station (HRS) applications enable ease of mind in refueling. We support H35 and H70 architectures with maximum fueling performance at low power, exceptional temperatures and with a minimal footprint. All valves are supplied with operating instructions and CoC (CE/PED, IECEx, ATEX, Nepsi, CCC and more). Availability and reliability are key differentiators of all Seitz valves. Every hydrogen valve is fully tested on an automated test bench for function and leakage with hydrogen forming gas. With our deep application engineering knowledge, we can integrate our premium solenoid valves in system modules, tailored to our customers' needs. The SeitzValve team is ready for your challenges. Do not hesitate to contact us, we are happy to help you build a hydrogen economy.
