PILOT-OPERATED GAS PRESSURE REGULATORS
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.
