Shut-off valves for hydrogen applications

Hydrogen offers a promising solution for meeting the world’s growing demand for renewable energy. Hydrogen can reduce global CO2 emissions and generate clean energy without harmful pollutants or by-products.


Wasserstoff ist hocheffizient

Hydrogen is highly efficient, versatile and adaptable, making it an ideal alternative to conventional energy sources. Moreover, hydrogen offers a wide range of applications in numerous industries - from transportation to manufacturing and beyond.

GEFA Processtechnik is your reliable partner for hydrogen applications. Our experts have extensive experience with promising media, such as hydrogen.


Von kompakt bis Hochleistung

Shut-off valves from DN8 to DN800 - From compact to high performance

As the importance of hydrogen technology as a sustainable energy source increases, so does the need for industrial valves for hydrogen applications that require high purity hydrogen. GEFA Processtechnik offers the ball valve DG and the high-performance butterfly valve HG for hydrogen applications.
Hydrogen systems require specific consideration during planning and operation. The valve as a safety component of a hydrogen system must fulfill important criteria, which relate to:

  • Tightness inside (completely leak-tight),
  • Tightness outside (technically permanently tight),
  • High pressure resistance and
  • Resistance to hydrogen embrittlement

Kugelhahn 1

BALL VALVE DG for hydrogen applications

Our ball valves are characterized by a compact design and a full flow for ultra-pure media. Due to the variety of variants, the ball valves can be adapted to your applications and requirements.

Sizes: DN8 - DN150 | Pressure classes: up to PN125

Automation

  • Standard mounting flange according to EN ISO 5211
  • Direct actuator mounting without interruption of the stem
  • Pneumatic, electric or manual actuation is possible
  • Dead volume reduction through dead space filling seat rings

Connections

  • Butt weld end, short
  • Butt weld end, long
  • Orbital weld ends
  • Threaded end / female thread / NPT
  • Full bore / reduced bore
  • Welding flanges

Hochleistungsklappe 1

HIGH PERFORMANCE BUTTERFLY VALVE HG for hydrogen applications

Butterfly valve based on double eccentric principle for low-friction operation.

Sizes: DN50 - DN800 | Pressure classes: up to PN40

Automation

  • Standard mounting flange according to EN ISO 5211
  • Direct actuator mounting without interruption of the stem
  • Variable and exchangeable for any actuator size
  • Actuator protection against leakage

Safety

  • Stem sealing can be re-tensioned beneath the mounting flange; thus, it can be readjusted without dismounting the actuator
  • Live loaded packing

Connections

  • Intermediate flange valve that can be flanged on both sides
  • Double flange variant


Hochleistungsklappe 2

Advantages of the high performance butterfly valve HG

  • Reliable sealing against high pressures and low torques due to the double offset design
  • Low-wear switching characteristics
  • GEFA-MULTITOP Efficient automation with variable interface without interruption of the stem
  • Ease of maintenance
  • Pivoting angle limitation and optical position indicator at the stem prevents wrong position of the stem during servicing
  • different cleaning standard
