<p>The present invention comprises a dump valve assembly to drain a tank. The dump valve assembly has a drain (11) at a bottom of the tank, a cap (20), a sealing plate (30) and an actuator (40). The drain has a flanged end (12). The cap has a base and a side, the side having an inward protrusion. The cap can be removed from the drain by simply disengaging the protrusion from the flange. The sealing plate contacts the end of the drain opening to seal the drain. The actuator drives the plate away from the cap base to place the plate surface against the drain end to close the dump valve assembly and drives the plate toward the cap base to remove the plate surface from the drain opening to open the dump valve assembly.</p> |
