A two-stage valve assembly for a vehicle lift system comprises an outer sleeve (24) extending along an axis (A) between a first end (26) and a second end (28). A stator (30) is located in the first end and a valve opening (40) is located in the second end. The two-stage valve assembly includes an armature assembly (32) for selectively closing and opening the valve opening in a first-stage open position and a second-stage open position. The armature assembly comprises a plunger (62) moveable along the axis that includes a poppet portion (66) having a poppet seal oriented towards the second end. A plunger seat (72) is moveable along the axis being located between the poppet portion and the valve opening. The plunger seat includes a seat seal for sealing against the valve opening. A seat channel extends through the seat seal and the plunger seat and is in fluid communication with the valve opening.
