7.4. Hydraulic specifications
•
Leave appropriate space to facilitate the assembling/dismantling and maintenance operations.
•
Before the installation, wash the pipes properly to eliminate any residual. Not washing the
pipes properly can compromise the valve functioning.
•
Install a resilient seat gate valves upstream and downstream the valve in order to facilitate
maintenance operations.
•
Install the valve on the pipeline, checking the arrow printed on the valve must follow the water
flow. Use the eyelet on the cover to lift or lower the valve.
•
The valve should be installed in a horizontal position with the cover up; other positions are also
possible but must be verified with our Technical Office.
•
Make sure the valve position permits to easily dismantle the hydraulic circuit or its components.
•
After the installation, check there are not damages to any joint, pipe or tools.
The hydraulic pressure reducing valve is an automatic control valve specifically designed to
maintain outlet pressure constant at a defined value. Independently from the pipeline pressure
variations or variations in the water demand.
