Check Valve (NRV)

The Check Valve (NRV) is a high-performance non-return valve designed to allow water flow in one direction while preventing backflow in fire protection, water supply, and industrial piping systems. It helps reduce water hammer, protects fire pumps, and ensures reliable system performance. Ideal for fire pump discharge lines, sprinkler systems, and commercial or industrial applications.
