Abstract:
A valve apparatus includes substantially co-aligned first and second valve seats and substantially co-aligned first and second valve members. The first valve member is moveable relative to the first valve seat between at least an open position in which the first valve member is spaced from the first valve seat and a closed position in which the first valve member is seated against the first valve seat. The second valve member is moveable relative to the second valve seat between at least an open position in which the second valve member is spaced from the second valve seat and a closed position in which the second valve member is seated against the second valve seat. An armature is operable for moving the first and second valve members, in response to a magnetic field generated by a coil.
