Air Compressor Non Return Valve (NRV) / Check Valve

A Non Return Valve (NRV), also known as a Check Valve, is a crucial component in an air compressor system. Its primary function is to allow airflow in one direction while preventing it from returning in the opposite direction. This ensures that compressed air does not flow back into the compressor when it’s not running, which could damage the compressor and cause inefficiencies in the system.

The Non Return Valve (NRV) or Check Valve typically consists of a spring-loaded disc or ball that sits against a seat. When the compressor is operating and generating compressed air, the pressure pushes the disc or ball away from the seat, allowing air to flow through. When the compressor stops, the pressure equalizes, and the spring pushes the disc or ball back onto the seat, preventing air from flowing back into the compressor.

Regular maintenance and inspection of the Non Return Valve (NRV) or Check Valve are essential to ensure its proper functioning. If the valve fails, it can lead to issues such as loss of pressure, reduced efficiency, and potential damage to the compressor. In some cases, the valve may need to be replaced if it becomes worn or damaged.
