High Pressure Piston Regulators
RPGX Series
Introduction
RPGX Series High Pressure Piston Regulators feature a single-stage pressure reduction design with a piston sensing mechanism that is more resistant to damage caused by pressure spikes. These regulators offer a wide outlet pressure range, with a maximum inlet and outlet pressure of up to 10,000 psig.
With eight port configuration options, these regulators are ideal for high pressure, low flow applications.
Features High Pressure Piston Regulators RPGX Series
◎ Built-in 40 μm inlet filter for cleanliness and extended service life
◎ Optional self-venting feature
◎ Drain port design allows residual liquid media in the downstream pipeline to be vented to a designated location
