  • Product Detail


VITAL VALVE Full Port Wafer check valves provide more flow and lower pressure drops than conventional Wafer check valves. Wafer Check Valve are retainerless design.
Wafer check valves have a body with a very thin "wafer" profile that makes them an ideal check valve for applications that require valves with short takeout lengths. Similar in operation to a swing check valve, the wafer check has a disc and seat arrangement that performs the check action.
Dual plate wafer check valve are supplied retainerless as standard. Our patented design does not have any threaded plugs in the pressure boundary and totally eliminates the potential leak path to atmosphere. This design meet fugitive emission control.
Wafer check valve are designed to API 6D or API 594.

APPLICATIONS:

· Petrochemicals

· Refining

· Nuclear

· Pulp & Paper

· LNG & Cryogenics

· Fossil & Cogeneration Power
