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).

Applications

• Water/Wastewater: Pump discharge lines.

• Oil & Gas: Pipeline backflow prevention.

• Chemical Plants: Corrosive fluid handling.

• HVAC: Chiller and boiler systems.

Selection Notes

• Swing Check Valves: Best for low-velocity liquids.

• Lift Check Valves: High-pressure systems.

• Wafer Check Valves: Compact, for limited-space pipelines.
