The regulator flow data is provided to assist in determining the proper regulator for the required application. The data is given for reference purpose only. If additional information is necessary contact your local distributor or the Customer Service Department at:

Victor Equipment Co., P.O. Drawer 1007,

Denton Texas 76202-1007 Phone: 1-800 426-1888.

The regulator flow data was established by connect-ing a valve to the regulator outlet. The valve was opened and the flow rates measured. The amount of pressure drop is shown on the curves as the flow increases.

Example:

An SR 450D with an inlet of 2000 PSIG and an internal pressure setting of 125 PSIG (no flow) will flow 1000 SCFH, but the delivery pressure will drop to 115 lbs. As the flow increased to 2000 SCFH, the pressure will drop to 108 PSIG.

With an inlet pressure of 200 PSIG and an initial set-ting of 125 PSIG, the regulator will flow 1000 SCFH with a pressure drop to 98 PSIG. At 2000 SCFH flow, the pressure will drop to 78 PSIG.

If a delivery pressure other than the ones shown on the flow charts is required, use an average curve rate between the upper and lower pressures shown.

Cylinder Pressure Rise

Single Stage regulators have a rise (increase) in delivery pressure as the cylinder pressure decreases. Listed below is the amount of pressure rise (increase) per 100 PSIG decrease in cylinder (inlet) pressure.

The change in delivery pressure of a TWO Stage regulator from full to empty Cylinder (inlet pressure) is negligible.
