JIS-standard lift check (non-return) valve designed to prevent reverse flow and protect pumps and upstream equipment. The lift-type mechanism opens under forward pressure and closes automatically when flow stops or reverses, delivering dependable one-way operation and tight shut-off in typical utility circuits. Cast iron body provides a durable, cost-effective solution for water and other non-aggressive media. Manufactured to JIS 5K pressure class with flanged ends for secure mounting, consistent alignment, and service-friendly maintenance in industrial and marine pipe networks.
