To ensure that the tank remains sealed in the event of an
accident, the valve body incorporates a shear groove
designed to fail in such a way as to leave the internal part
of the valve closed and attached to the tank.
Comparison tests between the Cleanflow and the Highlift
footvalves conclude that there is a 38% increase in flow
and a 27% reduction in discharge time.
