Abstract: A body structure includes an inlet port that receives fluid from a delivery device, a top-fill outlet port that connects to a top-fill line in communication with a cryogenic tank, a bottom-fill port that connects to a bottom-fill line in communication with a cryogenic tank and a slider tube cylinder. A cylinder housing is connected to the body structure and has a pressure comparison cylinder with an upper volume and a lower volume, with the latter in fluid communication with a cryogenic tank. A piston slides within the pressure comparison cylinder and a piston shaft is connected to the piston. A pressure regulator is in fluid communication with the upper volume of the pressure comparison cylinder and the slider tube cylinder. A slider tube is connected to the piston shaft and slides within the slider tube cylinder. The slider tube cylinder directs fluid to a top-fill line through the top-fill outlet port when a pressure in the lower volume exceeds a pressure setpoint and fluid to a bottom-fill line through the bottom-fill outlet port when the pressure in the lower volume is below a pressure setpoint. An over-pressure member is positioned in the upper volume of the pressure comparison cylinder. The piston contacts the over-pressure member as the piston slides upward in the pressure comparison cylinder.
