A valve according to an example of the present disclosure includes a poppet head configured to move with respect to a valve outlet of the valve. A first spring is configured to be compressed with a force generated by fluid flow through the valve, and compression of the first spring allows the poppet head to move towards the valve outlet. A second spring is configured to allow the poppet head to move toward the valve outlet when compressed. A method for controlling fluid flow is also disclosed.
