Bottom loading valves, tank management systems incorporating the same, and methods for managing tanks

A tank management system comprising:

• a tank surrounding an interior;
• a vent valve coupled to the tank that actuates throughout a venting position and a non-venting position, wherein the vent valve communicates a vent position signal indicative of actuation of the vent valve;
• a bottom loading valve coupled to the tank, the bottom loading valve comprising a valve body that defines a fluid passageway and one or more lateral openings and a motor that moves a piston throughout an open position and a closed position, wherein, when the piston is in the closed position, the piston fully obstructs the one or more lateral openings from the fluid passageway;
• and
• a controller communicatively coupled to the vent valve and the bottom loading valve, wherein the controller executes machine readable instructions to:
• cause the vent valve to actuate to the venting position;
• receive the vent position signal;
• determine that the vent valve is in the venting position from the vent position signal;
• and
• cause the piston of the bottom loading valve to move to the open position after the vent valve is determined as being in the venting position.
