FRANKLIN 40NB Pressure Regulator Valve - SCR BSP

PETRO’s Model 664 Pressure Regulator Valve was designed to be used in conjunction with suction type dispensers connected to an aboveground storage tank.

The pressure regulator valve prevents fuel from flowing to the pumping unit and flowing out the vent tube of the self-contained dispenser when the pump is not activated.

The pressure regulator valve is a vacuum actuated valve which will not allow product flow until the suction of the pumping unit opens the valve allowing the product to flow to the dispenser. The valve will close by means of an internal spring when pumping is completed.
