53VML-0160
The OPW 53VML Ball Float Vent Valves protrude into underground storage tanks from OPW 233 Series Extractor Fittings at the Stage I vapor return riser pipe or tank vent line. During a product delivery, as the tank level rises, a counterweight stainless steel ball seats on the valve body and restricts flow of vapors back to the transport truck. As the vapors become compressed in the tank (ullage), product flow into the tank is severely restricted. The 53VML Series Ball Float meets the U.S. EPA 90% requirement for product flow restriction into underground storage tanks. The 53VML-0060 and 53VML-0065 are designed as "back-up" overfill protection for overfill prevention valves, and to minimize product mixing with underground manifold vent lines.

• Stainless Steel Counterweight Ball Float – Corrosion-resistant for a long service life. Counterweight ensures proper seating of the ball for precision “slow-down” of product flow into the tank.
• Vapor Flow Orifice - A “bleed” hole machined into the body of the valve, sized to properly “slow-down” the delivery flow rate.
• Duragard® Body Coating - Helps prevent rust and corrosion build-up for a smooth seating surface and long service life.
• Various Body Lengths - Accommodate virtually any size tank.
• 2" and 3" Body Sizes – 3" size increases vapor flow to reduce product delivery time.
• Easy Installation, Service and Testing - Both 2" and 3" valves install in OPW 233 Series Extractor Fittings and are easily removed for inspection or tank testing with OPW 89 Extractor Wrench.
• Compatible with 85% Ethanol (E85) or Methanol (M85).

708592901
The Defender Series™ overfill prevention valve (OPV) is a self-contained two-stage positive shut-off valve that prevents the overfill of an underground storage tank (UST) during a gravity-fed product delivery. The Defender Series™ OPV employs a revolutionary magnetically-coupled actuator system to provide positive shut-off. This unique method of shut-off eliminates any penetrations in the valve, making it both vapor- and leak-tight. The Defender Series™ OPV provides safe, rapid, and reliable fuel drops for the broadest range of fuel applications and environmental conditions. Simple to install, service, and test remotely, the Defender Series™ OPV is the industry’s most versatile overfill prevention valve. Defender Series™ overfill prevention valve with 10' (3048mm) top drop tube, 8' (2438mm) bottom drop tube

37-201218
The 37 when used in conjunction with the V421 Vent Valve, protects against overfill of the UST. Signals the tranport driver when the tank is filled to 90% capacity, in accordance with current EPA guidelines.

• Protects against overfill of USTs.
• Signals the transport driver when the tank is filled to 90% capacity, in accordance with current EPA guidelines
• Fuel levels force the ball to a seating position, which restricts the venting system and slows the delivery rate dramatically
• Alerts the transport driver to stop product drop
• Retro-fittable and allows easy extraction for tank testing
• Utilized in vapor recovery applications
• For use on gravity delivery only
• V421 includes cage sssembly
• Compatible with E-85
