Terval/R

Terval/R is one of the pilot-operated gas pressure regulators 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 Close according to the European Standard EN 334.
