a seal and poppet assembly including:
a cage including a seat defining an aperture along a longitudinal axis;
a poppet disposed inside of the cage and movable along the longitudinal axis between an open position spaced from the seat to allow fluid communication through the aperture and a closed position that engages the seat to close the aperture; and
a spring latch fixed to the cage and releasably engageable with the poppet to hold the poppet in an intermediate-open position in which the poppet is spaced from the seat to allow fluid communication through the aperture, wherein the intermediate-open position is disposed between the open position and the closed position, and
wherein the spring latch releases from the poppet when the poppet moves from the intermediate-open position to the open position.
