Non-Return Valve (NRV)

Non-Return Valve (NRV) is used in water pipelines, fire hydrant systems, and pumping systems to control the direction of water flow. It allows water to move in one direction and stops it from flowing back through the pipeline. This makes it an important part of many water and fire protection systems.

The valve is commonly installed near pumps and in pipeline systems where reverse water flow can cause problems. Its simple working design makes it suitable for fire hydrant systems, water supply lines, pump rooms, and industrial piping. It is a practical choice for buildings and projects that need reliable water flow control.

Key Features

• Prevents Backflow: Stops water from flowing back through the pipeline.

• One-Way Water Flow: Allows water to pass in the required direction.

• Reliable Construction: Designed for regular use in water and fire protection systems.

• Suitable for Pump Systems: Commonly used in pump discharge and water pipelines.

• Easy to Use: Works automatically with changes in water flow.

• Fire System Compatible: Suitable for fire hydrant and other fire protection piping.

• Multiple Size Options: Available in different sizes for various pipeline requirements.

• Low Maintenance: Simple design makes inspection and maintenance easier.
