A solenoid actuated valve assembly comprising first and second valve members, first and second valve seats, a first spring biasing the first valve member to engage the first valve seat, a second spring biasing the second valve member to engage the second valve seat, and a solenoid coil, and wherein the first and second valve members include an armature mechanism effective when the coil is energized with a selected current to displace the first valve member from the first valve seat while the second spring maintains the second valve member in engagement with the second valve seat, the armature mechanism being further effective when the coil is energized with a current higher than the selected current to displace both the first valve member from the first valve seat and the second valve member from the second valve seat.
