- Recommendations for the installation
- Place a strainter upstream of the valve with a porosity £ 100 m.
- Mount the valve preferably on a horizontal pipeline with coil upright.
- The valve input pressure must always be > to the output pressure.
- In order to allow the normally closed or normally open valve to open, the minimum pressure indicated for each model must be respected.
