Aperval 101

Aperval 101 is one of the pilot-operated gas pressure regulators produced by Pietro Fiorentini.

Aperval 101 regulator is suitable for use with previously filtered non-corrosive gases, and it is mainly used for medium and low pressure natural gas distribution networks.

Aperval 101 regulator is classified as Fail Open according to the European Standard EN 334.
