ABSTRACT:
A mixing valve (10) has a control stem (22) for adjusting the movable ball valve (20) for controlling the flow rate and temperature mix of the mixed water. A spring clip (100) is mounted onto a rotatable disc member (70) retained on an upper fixed member (27). The plate member (70) has a slot (74) that receives the control stem (22) of valve element (20). The spring clip (100) has arms (102) with inwardly extending projections (114) that laterally engage the stem (22) to increase the operating force of the mixing valve when the mixing valve is at a preset flow position. The spring clip (100) rotates with the disc to cause no effect upon the temperature adjustment of the ball valve (20).
