Aperval 101
Description
Aperval 101 is one of the pilot-operated gas pressure regulators produced by Pietro Fiorentini.
This device is suitable for use with previously filtered non-corrosive gases, and it is mainly used for medium and low pressure natural gas distribution networks.
It is classified as Fail Open according to the European Standard EN 334.
