one stage regulators
two stage regulators
one-stage or two?

-single stage or one-stage regulators are designed for situations where small changes in delivery pressure are acceptable as the cylinder pressure decreases.

-dual stage or two-stage regulators are recommended when small fluctuations in delivery pressure are not acceptable.  two stages of pressure reduction ensures you maintain a constant flow as the cylinder pressure decreases.

two stage cylinder regulator

standard configuration

all regulators are sold complete with  an inlet cga connection, two gauges, a diaphragm packless outlet shutoff valve and an outlet tube fitting.

recommended applications

the two stage cylinder regulator is recommended where delivery pressure must be maintained constant as the cylinder pressure decreases. these regulators are ideally suited for continuous withdrawal of gas from pressurized cylinders.

brass bodies are recommended for non-corrosive gases.  316l stainless steel bodies are recommended for mildly corrosive gases.

  description

all our regulators are precision manufactured from machined bar stock. this design minimizes contamination of the gas stream from in-board diffusion of atmospheric contaminates. the design also minimizes cross-contamination of the gas stream that is frequently encountered with less expensive forged body regulators.
