Atlas Pressure Regulating Valve 1604084785 for Air Compressors

A Pressure Regulating Valve (PRV), also known as a Pressure Reducing Valve (PRV) or Sustaining Valve, is an automatic control device designed to maintain a constant lower output pressure regardless of fluctuations in the upstream (inlet) pressure or downstream flow demand. It is the fundamental component for creating stable, controlled pressure zones within larger systems, ensuring equipment receives the correct pressure for safe and efficient operation.

• Precise Pressure Control: Maintains a steady, pre-set downstream pressure (±1-2 PSI variance is common), providing stability for sensitive processes and equipment.
• Automatic Operation: Functions continuously without external power, using system pressure itself to actuate the valve via a diaphragm, piston, or spring mechanism.
• Equipment Protection: Safeguards downstream components from damage caused by overpressure, pressure spikes, or erratic supply pressure.
• Energy & Media Efficiency: Reduces compressed air, steam, or water to the minimum required pressure, eliminating waste and lowering operational costs.
• Robust Construction: Built from durable materials like brass, stainless steel, or carbon steel with corrosion-resistant components.
• Flexible Ranges & Options: Available in wide spectrum of pressure ranges, port sizes, and accuracy classes.
• Relieving & Non-Relieving Designs: Some models can bleed off excess downstream pressure for maximum stability.

The valve operates on a simple principle of force balance:

1. Set Point: A spring is adjusted to exert a specific closing force, corresponding to the desired downstream pressure.
2. Below Set Point: Reduced force on the diaphragm allows the spring to open the valve, increasing flow and raising downstream pressure.
3. Above Set Point: Increased force on the diaphragm compresses the spring, closing the valve and reducing flow to lower pressure.
4. Equilibrium: The valve modulates continuously to maintain perfect balance between spring force and downstream pressure force.
