OPW 61fSTOP-1000T 2" NPT Overfill Prevention Valve with Cylindrical Float can be used in gravity drop provided the minimum flow rate is maintained. A tight shut off is not achieved in the closed position. However with a minimum tank size of 1,000 gallons, the leak rate will provide a 30 minute warning before the tank is full.

Description

OPW 61fSTOP-1000T 2" NPT Overfill Prevention Valve with Cylindrical Float is designed to prevent overfilling of above ground storage tanks by providing a positive shut-off during a pressurized-fill (pump-on fill) delivery. “The Stopper” threads into the fill opening and is an integral part of the fill tube. The 2" 61fSTOP requires a 4" tank opening and minimum tank ullage (space from the top of the stored product to the inside top of the tank) of 8" on the 61fSTOP-1000T Cylindrical Float model. The 61fSTOP-1000T, with the cylindrical float, eliminates the need to position the valve to avoid tank walls or cross-bracing.

Features

  • A special crossbar tank-inlet adaptor is provided with each Stopper to provide for tight-fills and help prohibit open-fills
  • Completely Automatic Operation
  • Direct or Remote-Fill Compatible
  • Integral Anti-Siphon Valve - Drain vents on the 61fSTOP act as an anti-siphon, by introducing air/vapor into the fill line after the valve actuates, to help isolate the tank from a potential siphon due to a broken or leaking remote-fill pipe.
  • Pressure Rating: 150 psi (10 bar) with Low Pressure Drop – To enable quick, safe delivery of fuel into the tank
  • Flow Rate: 25 GPM (95 LPM)
  • The Stopper is a single-action, complete shut-off valve. When the liquid level rises to your specific, pre-determined tank capacity, the valve mechanism is released and automatically closes with the flow of the product. Any excess product left between the valve and the fuel delivery coupler is drained into the tank through internal drain vents.
