A flapper control valve having a valve housing and at least one valve port plate sealably secured to the valve housing. Each valve port plate has at least one valve port plate through hole. At least one back plate is mounted downstream from the valve port plate and in an open position at a distance from the valve port plate. Each back plate has at least one back plate through hole. In the open position, at least one valve port plate through hole is in communication with at least one back plate through hole. The distance between the back plate and the valve port plate in the open position can be closed thus sealing the communication between at least one valve port plate through hole and at least one back plate through hole.
