Compact Piston Regulators
RPCC Series
Introduction
RPCC Series Compact 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. These regulators are ideal for high-pressure, low-flow applications.
Features Compact Piston Regulators RPCC Series
◎ Compact and small size design
◎ Integrated 40 μm inlet filter for cleanliness and extended service life
◎ A variety of O-ring material options for broad media compatibility and temperature ranges
