Overfill Prevention Valve - DS Series

The 2” Morrison Overfill Prevention Valve is designed for use on low profile top loading storage tanks that require a high level shut-off. Once the product reaches the preset level the valve will close and allow minimal liquid to pass through to relieve the fill line pressure. The valve can be retrofitted on existing tanks and fits into a 2” opening. This valve accepts a 1½” male threaded drop tube (not included).

For use on clean liquids only. Not suitable for motor oil.
