General Piston Regulators
RPGC Series
Introduction
RPGC Series General 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. With eight port configuration options, these regulators accommodate a variety of gas and liquid applications.
Features General Piston Regulators RPGC Series
◎ Built-in 40 μm inlet filter for cleanliness and extended service life
◎ Optional self-venting feature
◎ The bonnet includes a captured vent port, allowing media to be vented to a designated location in the event of accidental O-ring failure
