Victor Edge 2.0 regulator combines flow and pressure regulation

Victor, an ESAB brand, has launched the Edge 2.0 ESS32 PFH-580 pressure/flow hybrid regulator, redesigned to allow for higher flow performance during pressure testing, resulting in systems that pressurize faster and improve productivity, the company reports. Designed for three common HVAC applications—brazing, purging, and pressure testing—the regulator combines flow and pressure regulation functions in a single device.

The unit features a patented, dual-stage gas flow orifice. The first-stage orifice enables lower flow rates. When the flow rate applies sufficient back pressure, it pushes open the first-stage orifice poppet, which then allows gas flow to bypass the smaller first-stage orifice and flow through a larger, second-stage orifice at higher flow rates and pressures.

The new design adds a flow bypass to the dual-stage mechanism, which opens once the regulator enters the pressure test range. As a result, flow in the second-generation design offers an approximately 500% to 1,000% increase in flow over the original design, depending on test pressure.
