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.
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.
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
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
Advantages of the ball valve DG
- Operationally proven and reliable design even in case of high pressures
- Ease of maintenance: very quick replacement of seals due to the center section, which can be swiveled out
- different cleaning standards

Application example:
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
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
