Sealum Industries offers check valves in three cracking pressures, 5 PSI, 30 PSI, and 50 PSI. The poppets are machined from 4140 heat treated steel, while the seats are machined from 65-45-12 cast iron. The bodies are stocked in C1018 steel, but are also available in 316 stainless steel upon request. The stem is welded to the poppet for a positive lock, and the entire assembly is held in the body with a retaining ring.
