Systems and methods for make-up air blocking valve with a restrictive poppet orifice

A valve comprising:

• a housing defining an inlet port and an outlet port in fluid communication with one another and defining a valve seat therebetween;
• a bell-shaped poppet sealing member seated within the housing, wherein the bell-shaped sealing member defines and orifice passing therethrough and has a bottom sealing surface defining a mouth thereof, and the bottom sealing surface when viewed in a longitudinal cross-section of the valve is a curved surface of a cone oriented radially upward and outward relative to a head of the poppet sealing member;
• a biasing member biasing the bell-shaped poppet sealing member into a normally open position;
• a commanded actuator connected to the bell-shaped poppet sealing member;
• wherein the commanded actuator is configured to move the bell-shaped poppet sealing member upon command from the open position to a closed position in which the bell-shaped poppet sealing member is seated against the valve seat;
• wherein, in the closed position, the orifice in the bell-shaped poppet sealing member defines a restricted flow path from the inlet port through the bell-shaped poppet sealing member to the outlet port.
