Check Valves (NRV)

Check valves (NRV) for preventing backflow and ensuring one-way fluid flow in your system.

Check valves, also known as non-return valves (NRVs), are designed to allow fluid to flow in one direction while preventing backflow. They operate automatically without the need for external control, using a hinged disc or ball mechanism that opens with forward flow and closes to block reverse flow. Ideal for protecting pumps and other equipment from damage caused by backflow, check valves ensure system integrity and operational efficiency by maintaining the correct direction of fluid movement.

Benefits

Prevents Backflow: Ensures fluid flows in only one direction, protecting equipment from potential damage caused by reverse flow.
Automatic Operation: Functions without the need for external control or manual intervention, providing reliable and hassle-free protection.
Enhances System Efficiency: Maintains proper flow direction, which helps in preserving system pressure and optimizing performance.
Protects Equipment: Safeguards pumps, compressors, and other components from potential damage and operational issues caused by backflow.
