Cast Full Port Lift Check
COOPER® Valves full port lift check valves are an excellent choice for applications where faster closing speeds are required to prevent surges. Cooper lift checks are built with an Inconel X-750 spring for extra strength and corrosion resistance. Cooper lift checks have a low differential pressure seal with a cracking pressure of 5 to 10 PSI. They can be supplied with a renewable disc with a Teflon insert good to -100 F or KEL-F insert good to -325 F.
