Abstract
A bleed air valve comprises a housing that includes an inlet, an outlet, and a center portion to selectively provide a pneumatic flow path between the inlet and the outlet. A piston moves along a center guide in response to forces applied to the piston, where the piston is spring biased to an open position. The valve also 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. A valve spring applies a force to the piston first surface to spring bias the bleed air valve to the open position. A solenoid valve 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.
