In the pilot-operated relief valve PVS 782 by Pietro Fiorentini, 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.
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.
