PCT No. PCT/US91/07816 Sec. 371 Date Dec. 8, 1993 Sec. 102(e) Date Dec. 8, 1993 PCT Filed Oct. 22, 1991 PCT Pub. No. WO92/22765 PCT Pub. Date Dec. 23, 1992.A ball type mixer valve (20) has a housing (25) and a ball valve element (11) mounted for pivotable motion about a longitudinal axis (A) of the housing (25) and a second perpendicular axis (B) that is fixed with respect to the ball valve element (11). The ball valve element has a control stem (10) extending therefrom and a pin (15) extending at a substantially perpendicular angle from the control stem. Two distal ends (16 and 17) of pin (15) form pivots which are received in slots (7) formed in the valve housing to position the ball vertically in the housing and allow the motion of the ball about the two defined axes.
