Piston Regulators High Flow
RPGN Series
Introduction
RPGN Series High Flow Piston Regulators feature a single-stage pressure reduction design with a piston sensing mechanism that is more resistant to damage caused by pressure spikes and offers a broad outlet pressure range, making them ideal for high flow applications.
Features Piston Regulators High Flow RPGN Series
◎ Large diameter piston improves pressure sensitivity
◎ Optional self-venting feature
