Gas isolation
Gate and ball valves can be reviewed for positive isolation where pressure, seat construction and leakage requirements are clearly defined.

HYDROGEN & INDUSTRIAL GAS
Forged valves for hydrogen & industrial gas applications
Hydrogen and industrial gas service requires the exact medium, pressure, temperature, material compatibility, sealing concept and leakage requirement to be reviewed before a valve construction is accepted.
APPLICATION OVERVIEW
Valve selection starts with the service conditions.
Industrial gas systems may handle hydrogen, nitrogen, oxygen, argon or other gases under very different purity, pressure and temperature conditions. A generic gas-service label is not enough to confirm valve suitability.
For hydrogen in particular, material selection, sealing, leakage expectations and any project-specific test or emissions requirement should be stated clearly. FerraForge treats these as application inputs and confirms the offered construction against the enquiry rather than assuming universal suitability.
TYPICAL DUTIES
Where forged valves fit into the application.
Pressure and flow control
Globe valves can be considered for manual regulation duties where the process requires controlled flow rather than simple quarter-turn isolation.
Non-return protection
Check valves provide automatic reverse-flow protection where backflow could affect compressors, storage, process equipment or adjacent gas systems.
Packaged gas systems
Compact forged constructions can suit skids and high-pressure packaged systems when materials, cleanliness, testing and end connections are specified.
SELECTION CHECKLIST
What should be confirmed before quotation?
- Exact gas or gas mixture, purity requirements and any cleanliness or oxygen-service preparation requirements defined by the customer.
- Design and operating pressure and temperature, including compression, expansion and start-up conditions.
- Body, trim, ball, seat, packing and bolting materials reviewed for the stated medium and service conditions.
- Required leakage performance, seat construction, emissions criteria and test medium.
- End connection, bore, cavity and operating arrangement appropriate to the installation.
- Hydrogen service, oxygen service and other special gas duties must be explicitly specified and technically reviewed; they should never be inferred from a generic valve designation.

Forged ball valves
Fast quarter-turn isolation with seat and sealing materials selected for the specified gas duty.
FREQUENT QUESTIONS
Application questions we review during valve selection.
Are standard forged valves automatically suitable for hydrogen?
No. Hydrogen suitability must be reviewed for the exact pressure, temperature, materials, seals, leakage requirement, manufacturing route and project specification before the valve is confirmed.
What should be specified for an industrial gas valve enquiry?
State the exact gas or mixture, purity, design and operating pressure and temperature, size, connection, materials, leakage criteria, cleaning requirements, testing, documentation and quantity.
Can one valve construction be used for every industrial gas?
No. Different gases can require different material, cleanliness, seat, packing, leakage and testing considerations. The exact medium and service conditions must be reviewed individually.
