Description

Pietro Fiorentini Norval pressure regulators are direct-acting devices for low and medium pressure applications controlled by a diaphragm and counter spring.

These PF Norval regulators are suitable for use with pre-filtered, non-corrosive gases.

PF Norval is characterized by a quick response to varying operating conditions. This makes it particularly suitable for use when serving ON-OFF burners and in any industrial process characterized by a quick change of the flow rate.

Pietro Fiorentini Norval Regulators

Its features of good accuracy of regulation, even in presence of significant variations of the upstream pressure and/or flow rate, make the Norval regulator also particularly suitable in distribution networks for civil use.

The Norval regulator, in its basic version, is classified according to the European standard EN 334, as a regulator which reacts in opening (Fail to Open). It is Truly a TOP ENTRY design, which confers to the regulator management advantages, for example the ability to performs full maintenance without uninstalling it from the connection pipe.
