Aperval 101
Pilot-operated gas pressure regulators

Aperval 101

The APERVAL 101 is a pilot-controlled regulator for low- and medium-pressure applications. The APERVAL 101 is a fail-to-open regulator.
It will open if:
•    There is no  pilot loop supply;
•    The  main pilot diaphragm is damaged.
This regulator is suitable for use with previously-filtered, non-corrosive gases.
Its truly "top entry design" allows all  maintenance to be carried out  without taking  the body off  line.
