An arrangement for temperature control and volume control of a pressure balancing valve used in tub/shower installations includes a temperature control handle that controls the mix of hot and cold water issuing from a pressure balancing cartridge within the valve and a volume control handle that controls the volume of the hot and cold water issuing from the cartridge. The volume control handle is connected to three lobes extending radially about the end of a shaft to which that handle is attached, the lobes being closely adjacent the face of the cartridge from which the water flows. The cartridge has a hot water outlet and a cold water outlet and in the neutral position of the volume control handle one of the lobes is located between the cartridge outlets and the other lobes do not block the outlets. When the valve is in operation one can rotate the temperature control handle to set the desired water temperature and one can rotate the volume control handle to set the desired water volume flowing from the cartridge. The two control handles are interconnected for conjoint movement so that when the temperature control handle is rotated to its "off" position to stop water flow the volume control handle is rotated back to its neutral position.
