VN 500 Nitrogen Purge Regulator, High-Precision Nitrogen Purge Control Valve with 500 PSI Test Pressure, 2-Position Flow Control, and Rustproof

Excellent Construction: The nitrogen purge regulator integrates a flow meter and pressure regulator, allowing for precise adjustment of nitrogen flow (up to 500 psi) for leak testing. Its hybrid design ensures efficient purging with controlled pressure and flow rates. Reliable Performance: Constructed with a robust brass valve body, this flow meter nitrogen purge regulator resists abrasion, high pressure, and wear. It maintains reliable performance even in demanding field conditions. Operating Modes: The nitrogen purge control valve offers preset functions (BRZ, OFF) for custom purging or brazing. Its 1/4" SAE threaded design ensures seamless integration into systems. Convenient Design: Using this pressure regulator reduces the risk of oxidation and moisture ingress, protecting refrigeration systems from acidification and extending equipment life. Optimized Efficiency: The integrated design The flow meter and regulator minimize energy waste by maintaining a constant nitrogen pressure, thus improving the overall reliability of the system during purging operations.
