PRIMUS 400979 Direct-Acting Pressure-Reducing Valve PCV01 – 6252

The PRIMUS 400979 is a direct-acting pressure-reducing valve, model PCV01, used in gas-delivery systems where regulated outlet pressure must be maintained independent of inlet pressure variation. The valve is a passive mechanical component with no electrical input; it reduces supply pressure to a preset outlet pressure as gas flows through the valve body. Typical applications include oxygen and medical-gas delivery lines in clinical environments.
