DIAPHRAGM SENSING TWO STAGE PRESSURE REGULATORS (SV – 100)

This series is designed for use in applications requiring constant outlet pressure even with wide variations in inlet pressure. This two-stage regulator is comparable to two single-stage regulators connected in series. The first stage is factory set to reduce the inlet pressure to 500 PSI-G (34.4 BAR-G). The second stage can be adjusted with the handle to achieve the required outlet pressure. This two-stage arrangement minimizes the supply-pressure effect caused by fluctuating inlet pressure, such as with a depleting gas cylinder. As inlet pressure drops below the setting of the first stage, the regulator then functions as a single-stage regulator. The first-stage pressure setting can be reduced while monitoring the pressure at the inter stage port, but lower flow may result.
