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.
