Designed for Above Ground Storage tanks requiring high flow fill rates.

Mechanical Overfill Prevention Valves

Designed for AST's requiring high LPM flow rate, the UL Listed , 2x3, 3x4, 4x6 are easily installed in 3,4 & 6 inch openings respectively.

Flow rates are as follows:

  • 2x4" - 300LPM
  • 3x4" - 400LPM
  • 4x6" - 800LPM

These valves are rated for fuel delivery up to 100 psi and provides positive fuel shut off at high fill rates. Entirely mechanical in operation, it can be used in remote fill applications, retrofitted to an existing AST, and has a unique drain back system designed to allow the delivery hose to be emptied after fuel delivery has been stopped. Materials used in the construction include:

  • Hard anodized 356-T6 Aluminum
