High purity regulators constructed for use with non-corrosive gases.

Applications

• Supply of carrier gas/detector support gas for gas chromatography applications.
• Calibration of pressure gauges, rotameters, and mass flow controllers.
• Applications where a constant delivery pressure is required.
• Applications with high duty cycle/demanding operating conditions. 

Design Features

• Chrome plated forged brass body
• Stainless steel diaphragms (1st and 2nd stages)
• 2” inlet and delivery pressure gauges
• Equipped with outlet diaphragm valve
• 1/4” NPTF outlet connection
• One-piece encapsulated seat with (10µ) internal filter to protect against contamination

*Note: where CGA is replaced by the actual CGA number. Some CGA limitations may apply. (NI) for 1/4" FNPT inlet
