61SOR Remote-Fill

The OPW 61SOR is designed for two-point remote-fill applications, where the fill point is not directly over the UST. The valve is installed in the tank through a riser pipe directly over the tank. A window in the drop tube is aligned with the entrance of the fill pipe from the remote-fill location to allow product to flow into the drop tube and down through the valve. A riser seal prevents product from flowing into the tank from outside the drop tube. A “trap door” assembly installed in the riser above the tank provides access for a gauging stick. Trap door, adaptor and cap are included with 61SOR.

61SOC Coaxial

The OPW 61SOC is used for coaxial fill applications, tanks equipped with a single product/vapor return connection. The 61SOC replaces the standard coaxial fill drop tube in a 4" riser fill pipe.

Advantages of Overfill Prevention Compared to Overfill Warning System

• Completely Automatic Operation - Does not rely on the alertness or speed of response of the delivery attendant for certainty of overfill prevention.
• Keeps the Top of UST “Dry,” per EPA Requirements - Eliminating possible leaks at loose bung fittings and the need for double containment on vent lines.
• Does Not Rely on Pressure in the UST to Stop Flow - Allowing faster fill times and reducing spill risk.
• Speeds Delivery Operations - Product flows unimpeded into the tank until the hose “kick” that accompanies the valve shut-off provides a clear signal that the liquid has reached the shut-off level.
• Simple and Inexpensive Installation - In both two-point and coaxial fill applications, no additional excavation, manholes or vent piping are required.

 

Additional Features

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 reset point. Models of the 61SO are available to meet virtually any UST application including two-point, coaxial, poppeted coaxial and remote fill. Methanol approved models are also available. The OPW 61SO is approved by the New York City Fire Department. (Approval #4902).

71SO Vapor-Tight Remote Fill

The OPW Vapor-Tight Remote Fill is designed for two-point vapor-tight remote-fill applications, where the fill point is not directly over the UST. A CARB approved vapor-tight 61SO overfill valve is installed in the sump through a riser pipe directly over the tank. The 61JSK-4RMT Kit installed within a 4” Tee provides an anchoring mechanism by locking the 61SO overfill valve in the tank fill riser. The “trap-door” assembly installed in the riser above the tank retains access for a gauge stick. The 61JSK-4RMT Kit coupled with any Vapor-Tight 61SO Overfill Valve will work for this application.

Notes and Warnings

In order to prevent product spillage from the Underground Storage Tank (UST), properly maintained delivery equipment and a proper connection at the tight-fill adaptor are essential. Delivery personnel should be managed and trained to inspect delivery elbows and hoses for damaged and missing parts. They should always make certain there is a positive connection between the adaptor and elbow. If delivery equipment is not properly maintained, or the elbow is not securely coupled to the adaptor, a serious spill may result when the OPW 61SO closes, causing a hazard and environmental contamination. NOTE: The OPW 61SO is designed for use on tight-fill gravity drop applications only. Do not use for pressure fill applications.
