Overview

PVS 803 by Pietro Fiorentini is one of the pilot-operated relief valves where the opening and the closing of the main plug is controlled by a pilot. Pilot operated relief valves are very responsive to the variations of the line pressures delivering high accuracy.

Particularly suitable for high-pressure transmission systems and for medium pressure gas distribution networks, this device can be used with natural gas and previously treated, non corrosive gaseous fluids.
