Hydrogen valves from A. Hock
Since the 1970s, industrial valves from A. Hock have been used worldwide - also in hydrogen applications. To ensure that the control valves perform their tasks reliably and safely, the right choice of materials and technical know-how are the crucial factors for us during design and manufacture.
Safe valves, technically mature and with long service life
The demanding medium hydrogen will be used in more and more fields of application in the future. To ensure safe operation, all components that come into contact with hydrogen must be suitable.

| S2060 | 2-way valve | High pressure single seated | PN63, PN160 / ANSI600, ANSI900 | DN15 - DN100 | 0,01 - 170 |
| S9000 | 2-way valve | Cage guided plug | PN40, PN160 / ANSI600, ANSI900 | DN15 - DN300 | 0,01 - 1400 |
| S2003/13 | 3-way valve | Allrounder | PN16, PN40 / ANSI300 | DN15 - DN300 | 2,5 - 1200 |
| S1003/13 | 3-way valve | HVAC application | PN16, PN25 / ANSI300 | DN15 - DN80 | 2,5 - 100 |
| V5066 | 3-way valve | Thermal oil application | PN16, PN25 | DN15 - DN80 | 2,5 - 100 |
Good to know: Each of our valve series can be flexibly adapted to the needs of hydrogen applications. Whether pneumatically or electrically actuated, we offer them the widest possible choice of actuators for your application.
You can count on it!
The H2-ready valves from A. Hock ...
- can prevent hydrogen embrittlement due to the smallest number of casting defects
- are safe, even at high pressures
- have low leakage values
- allow finest flow control up to KVS 0,01
- are approved or tested according to TA-Luft, DGRL, NACE
- have a long service life
- are exclusively equipped with high-quality materials

- are in short: H2-ready!
Applications for hydrogen valves
The application areas of our hydrogen valves are diverse: from chemical, pharmaceutical, nuclear to food industry. From steel production to use in the oil and gas industry. Everywhere the hydrogen resistant valves from A. Hock control the processes.
Experience in handling the critical medium hydrogen
For decades, control valves from A. Hock have been controlling processes in numerous industrial plants. We have mastered the functional principles of our standard products like no other. What distinguishes us beyond that is the manufacture of customer-specific products: Valve solutions such as hydrogen valves, including the associated electronic or pneumatic actuators - tailored to the respective requirement and at competitive prices.
