High-Pressure Valve Selection up to 10,000 bar
A checklist: pressure alone is not enough to choose a valve.
When selecting a high-pressure valve, the operating pressure, the fluid, the temperature, the type of actuation and the connection are evaluated together. Valve, fittings and tubing should also belong to the same pressure class.
Selection checklist
- 1
Operating and test pressure
Define the maximum operating pressure and the test pressure; the valve range must cover both.
- 2
Fluid and material compatibility
Check the fluid and material. In hydrogen service, material selection and the risk of hydrogen embrittlement are assessed separately.
- 3
Temperature range
Standard and high-temperature valve families cover different ranges; check the temperature limit together with the pressure.
- 4
Actuation
Hand, air-operated (piston or diaphragm), motor-driven or control valves, depending on the process and the degree of automation.
- 5
Flow control and accuracy
Metering and micrometering valves for fine adjustment of small flows.
- 6
Connections and tubing
Fittings and tubing must match the valve connection and belong to the same pressure class.
- 7
Safety
Relief valves and rupture discs; check explosion-protection (ATEX) requirements where relevant.

Frequently asked questions
Which pressure class should I choose?
The valve, fittings and tubing must cover the maximum operating and test pressure of the system and belong to the same pressure class. The pressure range of each product is listed on its page.
Do hydrogen applications need special valves?
In hydrogen service, material compatibility, sealing and the applicable standards are assessed separately. Describe your application and we will guide you using the product ranges and the manufacturer's information.
How do I get a quotation?
Use the quotation form and include the information in the checklist above; the catalogue page number speeds up the evaluation.
