Check-Device Adapters for Cavagna Valves (Omeca) are mechanical safety devices designed to integrate a check valve function into LPG and other pressurized fluid systems. These adapters allow fluid to flow in only one direction, automatically blocking backflow in the event of a pressure drop or flow reversal in the system.
Used in conjunction with external spring safety valves, the Check-Device adapter allows the relief valve to be dismantled or replaced without interrupting the gas supply to the tank, ensuring operational continuity and greater safety during maintenance operations.
Valve Set
External spring safety valves must be used in conjunction with check-device accessories and the respective gasket.
