Two-stage regulators keep gas delivery consistent
Victor Technologies has introduced Victor® Professional EST4 EDGE™ series two-stage gas regulators for acetylene, oxygen, inert gases, CO2, methane, and hydrogen.
The regulators feature an efficient internal flow path to help improve consistency from full to empty cylinder. They reduce cylinder pressure to a delivery level in two steps. The first stage regulates high cylinder pressure to a lower working pressure; the second (adjustable) stage controls delivery pressure, which remains at set point until the cylinder is nearly empty.
The regulators meet or exceed all compliance testing requirements, including the ASTM G-175 promoted ignition test. They incorporate SLAM™ (shock limitation and absorption mechanism) technology into the adjusting knob to help protect the pressure integrity of the regulator and cylinder if the cylinder falls over. Gauges are built in and recessed into the body for protection. The high-strength zinc-aluminum alloy used for the housing cap provides nearly twice the yield strength of forged brass, the manufacturer reports.
