A split gate is movably mounted within a valve body along a valve axis between valve seats. The split gate has gates, each extending between one of the valve seats and the other gate. In an open position, gate holes register with a fluid aperture and the valve seats to permit fluid flow. In the closed position, the holes do not register with the fluid aperture to prevent fluid flow. The split gate valve also has a gate guide located in the body for moving the gates with respect to the valve seats along the fluid axis. The gate guide forces the pair of gates apart along the fluid axis and into contact with the valve seats in both the open and closed positions. The gates have axial play along the fluid axis when the split gate is between the open and closed positions.
