The valve also includes a first moveable poppet piece having a closed position against the poppet seat that closes the valve. At least one surge discharge port passes through the first moveable poppet piece. The valve also includes a second moveable poppet piece compressionally biased in a position to seal the fluid discharge port or ports in the first moveable poppet piece.
