OPW 61SO OVERFILL PREVENTION The OPW 61 SO Overfill Prevention Valve is designed to prevent the overfill of underground storage tanks by providing a positive shut-off of product delivery. The shut-off valve is an integral part of the drop tube used for gravity filling. The OPW 61 SO allows easy installation (without breaking concrete)and requires no special manholes. The OPW 61SO is a two-stage shut-off valve. When the liquid level rises to about 95%of tank capacity, the valve mechanism is released,closing automatically with the flow. This reduces the flow rate to approximately 5 gpm through a bypass valve. The operator may then stop the filling process and disconnect and drain the delivery hose.As long as the liquid exceeds the 95%level, the valve will close automatically each time delivery is attempted. If the delivery is not stopped and the liquid rises to about 98%of tank capacity,the bypass valve closes completely. No additional liquid can Flow into the tank until the level drops below a o F'W reset point. `` Models of the 61 SO are available to meet virtually any UST application including two-point, i -.4 coaxial, poppeted coaxial and remote fill. The 61SO-3000 provides two-point overfill protection for eesTIFI<elo► 3"riser pipes,and the 61SO-1000 and 61SO-100C (CARB)feature a grooved-tube design for use with tank gauging systems.
