Testable overfill prevention valve

摘要

An overfill prevention valve system including an overfill prevention valve having a blocking component. The blocking component is movable between a closed position, wherein the blocking component generally blocks fluid from flowing through the valve, and an open position, wherein the blocking component generally allows fluid to flow through the valve. The valve further including a float operatively coupled to the blocking component. The system additionally has an actuator that is operable to directly or indirectly move the blocking component to at least one of its open or closed positions to thereby enable testing of the overfill prevention valve.

1. An overfill prevention valve system comprising:
an overfill prevention valve including a fluid path and a blocking component positioned in the fluid path, wherein said blocking component is movable between a closed position wherein the blocking component generally blocks fluid from flowing through the fluid path and an open position wherein the blocking component generally allows fluid to flow through the fluid path, the overfill prevention valve further including a float operatively coupled to the blocking component and positioned externally of said fluid path; and an actuator that is manually operable to magnetically interact with and move the float, which movement of said float in turn causes the blocking component to move away from said open position to thereby enable testing of the overfill prevention valve.
