Product Description
Atlas Non-return Valve 8204094034 High Quality Screw Air Compressor Parts
Non-Return Valve - Product Overview
A non-return valve (NRV) or check valve allows fluid flow in one direction only, preventing backflow in pipelines. Commonly used in water, oil/gas, chemical, and HVAC systems to protect pumps, compressors, and other equipment.
Key Features
- Automatic Operation: Opens/closes based on flow pressure (no manual intervention)
- Low Pressure Drop: Minimal flow resistance in open position
- Versatile Designs: Swing, lift, ball, diaphragm, or wafer styles
- Leakproof Seal: Tight sealing when closed (metal-to-metal or soft seals)
