ABSTRACT:
A check valve mechanism is disclosed for a twin tower gas drying system. The drying system filters unpurified gas to supply purified gas to a pneumatic system. The purified gas is supplied alternately from each tower to the mechanism for distribution in an output percentage to the pneumatic system and in a purge percentage to the drying system for purging moisture previously collected. The mechanism includes a valve body and a shuttle choke. The body defines first and second channels connected to the first and second towers, respectively; a shuttle tube having first and second ends connected to the first and second channels, respectively; and an output passage having an initial end communicating with the pneumatic system and a terminal end communicable with the tube. The choke defines an orifice and slides between the ends. When purified gas flows from the first tower, the choke slides to the second end. Purified gas flows from the first tower through the first channel through the output passage in the output percentage to the pneumatic system and through the orifice in the purge percentage through the second channel for purging via the second tower. When purified gas flows from the second tower, the choke slides to the first end. Purified gas flows from the second tower through the second channel through the output passage in the output percentage to the pneumatic system and through the orifice in the purge percentage through the first channel for purging via the first tower.
