ASCO NUMATICS series R80 R82 R88 high precision and multi-stage pressure regulators ensure a longer service life thanks to the die cast zinc body and NBR diaphragms. The difference between each series is, standard version R80, high relief R82 and high flow version R88. A continuous bleed adjusts the pilot diaphragm causing appropriate movement of the valve.
