Abstract
This invention relates to a single-handled valve for controlling both combined volume and relative proportion of hot and cold water. A control valve stem extends between diametrically disposed moldable sealing members, the sealing members respectively cooperating with hot and cold water inlet openings. The axial and angular positions of the stem determine the combined volume and relative proportion while the sealing members perform all of the sealing functions between the inlet openings and the valve outlet.
