PF Aperval Pilot-Operated Gas Pressure Regulators

Aperval is a pilot-controlled pressure regulator for medium and low pressure applications.

•    If the  main diaphragm fails;
•    If there is no sensor line input .
This regulator is suitable for use with previously-filtered, non-corrosive gases.
