2) Opening the valve starts the draining process.
3) The valve closes again automatically when all the water at the bottom of the tank has been drained.
ADVANTAGES :
Eliminates product spills
Reduces operator exposure to hydrocarbon vapour
Valve closes immediately if products detected
Low maintenance cost
No outside energy needed
