Bulk storage & distribution
Extended-stem isolation valves, pressure-building and pressure-reducing configurations.
Industrial Gases
Valves for industrial gases.
Storage, distribution and process use all start with the gas. Select the valve for the named medium, fluid state and installation conditions.

The application
One installation. Several distinct duties.
Bulk-gas and process installations may need local isolation, automatic shut-off, pressure regulation, liquid-level connections and non-return protection. Oxygen, nitrogen, argon and carbon dioxide have different service requirements. The exact medium, phase and cleaning specification form part of the enquiry.
Process & production
Control valves, automated shut-off and check valves for the specified operating sequence.
Tank & line equipment
Liquid-level manifolds, strainers, couplings and pressure-relief selections.
Selection essentials
What defines the right configuration?
- Medium
- Name the gas and fluid state, composition and required purity.
- Oxygen duty
- Specify compatibility, cleaning, inspection and protective packaging.
- Operating cases
- Design pressure, minimum temperature and normal/maximum flow.
- Installation
- Pipe interface, available space, actuation and relief arrangements.
