Pietro Fiorentini Aperval 101 Regulator

The Aperval 101 is a pilot operated regulator for low and medium pressure applications. It is a fail-to-open regulator. It will open if there is no pilot look supply or if the main pilot diaphragm is damaged.  

The regulator is suitable for use with previously filtered non-corrosive gas. Its top-entry design allows all maintenance to be carried out without taking the body offline.
