Valves With Multi-Directional Ball Check

A valve comprising

• a valve body with a main passageway therethrough for fluid flow through the valve,
• a valve member positioned rotatably in the valve body for controlling fluid flow in the main passageway,
• the valve member having a member passageway therethrough and the valve member positionable in fluid communication with the main passageway of the valve,
• the member passageway having a first flow port at a first end of the member passageway and a second flow port at a second end of the member passageway, the first end spaced apart from the second end,
• a ball check movably disposed within the valve member in the member passageway, the ball check having a largest dimension,
• the valve member having a ball seat against which the ball check can seat to close off the member passageway to fluid flow to prevent fluid flow through the first flow port,
• the main passageway having a flow portion between the first flow port and the ball check, the flow portion having a flow portion dimension, the flow portion dimension smaller than the largest dimension of the ball check so that the ball check is not passable through the first fluid portion and is not passable out of the valve member,
• the valve member having retaining structure at the second flow port to retain the ball check and prevent the ball check from exiting from the valve member through the second flow port,
• the valve member positionable in three positions, the three positions including a first position, a second position, and a third position, each of the three positions different from the other two positions, the valve member selectively rotatable to one of the three positions,
• the first position different from the second position, the first position different from the third position, comprising a run position in which the valve member is positioned permitting fluid flow in a first direction through the valve from the first flow port to the second flow port and fluid flow in a second direction through the valve from the second flow port to the first flow port,
• the second position different from the first position, the second position different from the third position, the second position comprising a bypass position in which the valve member is positioned permitting fluid flow in the second direction through the valve from the second flow port to the first flow port, and
• the third position different from the second position, the third position different from the first position, the third position comprising a closed position in which the valve member is positioned to close the valve to fluid flow.

• the member passageway having a first flow port at a first end of the member passageway a second flow port at a second end of the member passageway, the first end spaced apart from the second end,
• a ball check movably disposed within the valve member in the member passageway, the ball check having a largest dimension,
• the valve member having a ball seat against which the ball check can seat to close off the member passageway to fluid flow to prevent fluid flow through the first flow port,
• the member passageway having a recess between the first flow port and the second flow port within which the ball check is restable with fluid flowing through the member passageway, the recess having a recess width, the recess is between the ball seat and the second flow port,
• the ball seat is adjacent the first flow port and the ball seat is spaced-apart from the second flow port, and
• the ball seat has an opening for receiving a portion of the ball check, the opening has a seat width smaller than the recess width.
