Abstract: A bleed valve system includes a bleed valve, a valve regulator, a valve actuator and a reverse flow relief valve. The bleed valve is opened and closed to control a flow of bleed air from an upstream inlet to a downstream outlet. The valve regulator provides a servo pressure used to regulate the position of the bleed valve, and the valve actuator is mechanically connected to open/close the bleed valve based on the servo pressure provided by the valve regulator. The reverse flow relief valve compares a pressure upstream of the bleed valve to a pressure downstream of the bleed valve and in response to the downstream pressure exceeding the upstream pressure creates a fluid communication path between the servo pressure and an ambient pressure to decrease the servo pressure such that the bleed valve is closed.

Abstract: A bleed air control valve includes a pneumatic actuator operable to drive rotation of a closure disk, a connecting rod, a shaft, and an actuator fluid supply passage. The pneumatic actuator includes an integral filter and pressure regulator unit disposed in line with the actuator fluid supply passage. The actuator fluid supply passage provides communication between an inlet side of the flow control duct and at least one pressure chamber. The integral filter and pressure regulator unit has a cylindrical regulator cavity in selective communication with a cylindrical vent cavity. Filter media is secured to the pressure regulator unit and disposed across at least one of a regulator inlet orifice and a regulator outlet orifice. A regulator nozzle has at least one regulator port providing selective communication between a vent cavity and a regulator cavity.
