Abstract
A modular valve cartridge for a regenerative air dryer including a housing having a dry air passage and a desiccant canister having a desiccant bed. The modular valve cartridge includes a cylindrical body having an air passage extending axially there through between a first opening and second opening, a first end of the cylindrical body, including the first opening, to releasably couple to the housing to place the cartridge air passage in communication with the dry air passage via the first opening, and a second end of the cylindrical body, including the second opening, to releasably couple to the desiccant canister to place the cartridge air passage in communication with the desiccant bed via the second opening. A check valve is disposed within the cartridge air passage, the check valve biased to be in a normally closed position to close the cartridge air passage and to open the cartridge air passage in response to receiving a pressurized air via the second opening.
