ABSTRACT:
An improved control valve for use in a mixing valve has a valve mount, a spindle assembly and a water restraining plate having two outlets. The spindle assembly has a spindle rod and a two staged valve body having a chamber at the lower portion thereof. In the chamber are a plurality of cylindrical posts, including four long posts and other short posts that are arranged in order. The cylindrical posts are used to reduce the noise of turbulent flow passing through the valve body and the four long posts support the water restraining plate in place and stop a spring biased sealing pad from dropping into chamber via the outlets. Thus, the spindle rod of the spindle assembly can be rotated more smoothly and the noise produced in operation can be minimized.
