The 66R vapor recovery regulators respond to changes in blanket gas pressure and throttle open or closed to control the flow of the blanket gas out of the vessel. A vacuum source on the outlet of the regulator can be used to increase flow capacity of low-pressure blanket gas out of the vessel into a vapor disposal or reclamation system. The Type 66R uses a pilot to decrease buildup and provide even higher accuracy.
