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.

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.
