Each valve has a housing defining a first port and a second port in fluid communication with one another and defining a valve seat therebetween. A biasing member biases a poppet sealing member into a normally open position (defining unrestricted flow through the valve) and a commanded actuator is connected to the poppet sealing member. The poppet sealing member has an orifice therethrough defining a restricted flow path, and, upon command, the commanded actuator moves the poppet sealing member from the open position to a restricted flow position in which the poppet sealing member is seated against the valve seat for restricted flow thorough the orifice in the poppet sealing member.",
