Used on AST to help prevent a release of product if rupture in the line occurs below liquid level in the tank. The 910ER is normally closed and will resist the head pressure and assist in preventing any "siphoning" of tank contents. 25 PSI. Note: Due to heavy spring load needed to resist head pressure, this valve is restricted to use on submerged pump (pressure) systems only.
