Pietro Fiorentini Aperval 101 Regulator

APERVAL 101 is a pilot controlled regulator for low and medium pressure applications. APERVAL 101 is a fail-to-open regulator.
It opens in case of:

This regulator is suitable for use with previously filtered, non-corrosive gases.
Its truly "top entry design" allows any maintenance operation without removing the body from the line.
