A low cost valve results from the use of a single machined part for a valve housing. The housing is made of a non-magnetic material which can be less expensive and eliminates the requirement for screens or filters in automotive applications. A tube stop is threadably connected to the valve housing eliminating the requirement of brazing in manufacturing. Finally, a biasing spring acting on a plunger pin eliminates the requirement for providing a counterbore in the plunger for maintaining the plunger and thus a valve member in the normal or unactuated position.
