Application Profile

Automotive Pressure Regulator Pin

A new valve design used in a fuel pressure regulator for a major automotive part manufacturer presented several challenges for manufacturability. First, the design of the valve seat limited the weight of the part, so to reduce weight, the material between the rubber seal and the spring had to be as thin as possible. Second, the rubber seal molded into the valve seat required compliance with a strict flatness specification of +/- .002” to ensure the rubber over-mold retention ring provided precise and repeatable seating.

Sussex Wire produced the part with a very thin wall meeting the flatness specs, while at the same time, actually improved the valve’s surface strength by virtue of work hardening the material property from the cold forming process. Production quantities exceed 4,000,000 parts per year, with no degradation of tooling or part compliance.
