Enclosed in the body is a sliding part called the shuttle. It is used to seal one of the two inlet ports. A shuttle seat is installed at each inlet port. During operation, the shuttle is held against one of these seats, sealing off that port. These parts are held in the body by end caps.
External leakage is prevented by an O-ring gasket at each end cap.
