A bleed air valve for an aircraft gas turbine engine, comprising: a housing that includes an inlet at a first end, an outlet at a second end, and a center portion between the inlet and the outlet to selectively provide a pneumatic flow path between the inlet and the outlet via a passage in the center portion; a piston that moves along a center guide, where the piston includes a first piston surface and an opposing second piston surface, and the piston moves along the center guide in response to forces applied to the first piston surface and the second piston surface, where the piston is spring biased to an open position such that the inlet and the outlet are in fluid communication; and a valve spring that applies a force to the first piston surface to spring bias the bleed air valve to the open position; characterised in that the bleed air valve further comprises: a pressure regulator valve that comprises a spring loaded poppet valve that includes a pressure regulator inlet that receives an inlet pressure which is regulated based upon force applied to a pressure regulator piston by a regulator spring to provide a regulated output pressure at a pressure regulator outlet that is in fluid communication with the piston first surface; and a solenoid valve that receives a command signal and in response provides compressed air to a solenoid valve outlet that is in fluid communication with the pressure regulator inlet, wherein when the solenoid valve is energized a solenoid ball valve is positioned to close the solenoid valve inlet, and when the solenoid valve is not energized the solenoid ball valve is positioned to provide a compressor discharge pressure at the solenoid valve outlet and thus the pressure regulator inlet receives the compressor discharge pressure via the solenoid valve outlet. a housing that includes an inlet at a first end, an outlet at a second end, and a center portion between the inlet and the outlet to selectively provide a pneumatic flow path between the inlet and the outlet via a passage in the center portion; a piston that moves along a center guide, where the piston includes a first piston surface and an opposing second piston surface, and the piston moves along the center guide in response to forces applied to the first piston surface and the second piston surface, where the piston is spring biased to an open position such that the inlet and the outlet are in fluid communication; and a valve spring that applies a force to the first piston surface to spring bias the bleed air valve to the open position; characterised in that the bleed air valve further comprises: a pressure regulator valve that comprises a spring loaded poppet valve that includes a pressure regulator inlet that receives an inlet pressure which is regulated based upon force applied to a pressure regulator piston by a regulator spring to provide a regulated output pressure at a pressure regulator outlet that is in fluid communication with the piston first surface; and a solenoid valve that receives a command signal and in response provides compressed air to a solenoid valve outlet that is in fluid communication with the pressure regulator inlet, wherein when the solenoid valve is energized a solenoid ball valve is positioned to close the solenoid valve inlet, and when the solenoid valve is not energized the solenoid ball valve is positioned to provide a compressor discharge pressure at the solenoid valve outlet and thus the pressure regulator inlet receives the compressor discharge pressure via the solenoid valve outlet. a pressure regulator valve that comprises a spring loaded poppet valve that includes a pressure regulator inlet that receives an inlet pressure which is regulated based upon force applied to a pressure regulator piston by a regulator spring to provide a regulated output pressure at a pressure regulator outlet that is in fluid communication with the piston first surface; and a solenoid valve that receives a command signal and in response provides compressed air to a solenoid valve outlet that is in fluid communication with the pressure regulator inlet, wherein when the solenoid valve is energized a solenoid ball valve is positioned to close the solenoid valve inlet, and when the solenoid valve is not energized the solenoid ball valve is positioned to provide a compressor discharge pressure at the solenoid valve outlet and thus the pressure regulator inlet receives the compressor discharge pressure via the solenoid valve outlet.
