Provides pressure or vacuum relief in applications that require vapors to be piped away in lieu of venting into the atmosphere. Depending upon orientation of connections, the pallet in the housing allows intake of air or release of vapors as the tank breathes normally. In the standard configuration, relieving vapors are piped away through a flanged connection one size larger than the inlet, providing greater flow capabilities. Same size outlet flange also available.
