Serving the gas industry worldwide
Features
- Completely independent operation of regulator and safety cut-off valve.
- Diaphragm casing can be rotated through 360º at intervals of 45º to assist servicing and installation in confined spaces.
- Both regulator casing/valve head and safety cut-off valve can be removed from the body as cartridges, ensuring straightforward maintenance without removing the body from the pipeline.
- Wide operational pressure range.
- Internally or Externally impulsed (ICL/ECL).
