ABSTRACT:
A valve for regulating fluid flow between a pair of angularly disposed passages. A valve body closely receives a valve member therein and both components are preferably formed of a polymeric material for corrosion protection. The valve member includes first and second grooves spaced therealong, and has a handle disposed at one end thereof. The first groove is of a generally elliptical conformation having a pair of arcuate portions disposed axially and approximately 180.degree. circumferentially from each other. A pair of interconnecting portions extend between the arcuate portions. A stiffener is included in the valve member for limiting deformation and deflection thereof during high fluid pressure conditions.
