Class 800 LB Check Valve

A Class 800 LB Check Valve is designed for pressure systems with a rating of approximately PN150, ensuring reliable operation under high-pressure conditions. These valves effectively control one-way flow, preventing backflow within industrial pipelines. Known as Non Return Valves or One Way Valves, they automatically allow fluid (liquid or gas) to flow in only one direction by opening with forward flow and closing to block reverse flow. This design protects mechanical equipment in piping systems without the need for manual or external control, typically lacking a handle or stem.
