Class 300 LB Check Valve

A Class 300 LB Check Valve is designed to prevent backflow in pipelines with a pressure rating equivalent to PN50. This type of valve operates as a one-way valve, allowing fluid to flow freely in one direction. When the flow direction reverses, the valve automatically closes to prevent backflow, thereby protecting piping, valves, and pumps from potential damage. It ensures the safe and reliable operation of industrial and commercial fluid handling systems by maintaining directional flow integrity under relatively low-pressure conditions.
