Pressure Regulators

Liquid Changeover System offers continuous gas flow.

Model 8404L Liquid ChangeOver Regulator System provides uninterrupted flow of specialty gases by directing flow from 2 separate dewars to point of use. When one source empties, system automatically draws from second source. Gas Saver circuit directs reserve dewar's accumulated head gas pressure to primary source where it can be used. Featuring powder-coated steel chassis, Model 8404L is...

Electronic Pressure Regulator delivers high relief flow.
Pressure Regulators

Electronic Pressure Regulator delivers high relief flow.

Offering reverse flow rates in excess of 25 scfm @ 100 psi, the QB3 electronic pressure regulator makes backpressure and high relief applications possible without use of a quick exhaust valve. It uses solid-state pressure sensor to monitor pressure at work port and electronically adjusts the integral regulator to desired pressure by filling or exhausting air from system. Product can be calibrated...

Pressure Regulators

Regulators control pressure and ensure gas purity.

Smart Indicating Regulator(TM) Series features purifier built onto output that prevents contamination of gas stream and serves as early warning of impurities. If gas contains contaminants, or if contaminants enter gas stream during cylinder change out, purifier media begins to turn color. When all media changes color, purifier is depleted and cartridge should be changed. Units include 2-stage...
