Abstract
A regulator valve has an anti-seize feature when in the hard stop position. The valve is providing with a biasing force away from the hard stop position when in the hard stop position sufficient to prevent seizure of the drive screw in the hard stop position. This biasing force may be provided by a resilient member and/or a plastic, instead of a metal, adjusting screw which may provide sufficient resiliency to prevent seizing in the hard stop position. A resilient member could be a washer such as a spring washer, a wave washer, or even a compressible flat.
