PVS 803 is the pilot-operated relief valve by Pietro Fiorentini in which the opening and the closing of the main plug is controlled by a pilot device which is very sensitive to the variations of the in-line pressures.

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