Victor Enhances Edge™ 2.0 Pressure/Flow Hybrid Regulator for HVAC/R Applications

Annapolis Junction, Md. – Victor®, an ESAB brand, has launched its improved EDGE™ 2.0 ESS32 PFH-580 pressure/flow hybrid regulator. The new design allows for significantly higher flow performance during pressure testing, resulting in systems that pressurize much faster and improve productivity. Designed for three common HVAC applications — brazing, purging, and pressure testing — the EDGE 2.0 PFH-580 combines flow and pressure regulation functions in a single device.

Traditionally, a regulator would either be a flow regulation device or a pressure delivery regulation device. To create a wide range of adjustability, Victor designed the newly patented dual-stage gas flow orifice. The first stage orifice enables lower flow rates. When the flow rate applies sufficient backpressure, 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 1000 percent increase in flow over the original design (depending on test pressure).

The EDGE 2.0 PFH-580 regulator provides adjustability between:

1. 3 – 6 CFH for using nitrogen as a backing gas when brazing
2. 20 – 50 CFH for nitrogen purge applications
3. 200 – 800 psi to conduct pressure tests

EDGE 2.0 DNA

For added clarity, the EDGE 2.0 PFH-580 regulator features a large diameter delivery gauge and uses a high-contrast, color-coded gauge face with labels for brazing, purge, and pressure test settings. The cylinder pressure gauge is smaller and offsets to create a difference in depth perception. Even from a distance, operators can tell if they have sufficient cylinder contents and if delivery pressure is within safe and acceptable ranges.

Like all EDGE 2.0 regulators, the PFH-580 features a sloping gauge guard, a modular gauge and provides safer operation through three primary design functions:

• Patented SLAM™ (Shock Limitation and Absorption Mechanism) technology built into the adjusting knob, permitting the knob to absorb the impact in the event of a cylinder fall.
• Compact, patented design styling that integrates the gauge into the regulator body for superior safety and protection.
• Incorporating a patented particle trap so the regulator could pass ASTM G-175 promoted ignition test.
