Independent Volume Control: Dual-control valve trims are what separate Delta showers from the competition. The top, smaller handle controls temperature, while the bottom, larger dial controls the water volume (flow rate). The distinct advantage to this is that you can set the temperature control to a temperature you like, and then leave it, turning the shower on and off each time with the volume control. You’ll never have to fuss with the temperature again. Monitor: Delta Monitor showers feature pressure balance valve cartridges, which protect against sudden temperature or pressure changes to keep the water in the shower within a safe +/- 3°F. Monitor valves also feature a high-temperature limit stop that can be adjusted to suit your shower needs. MultiChoice Valve: Flexibility is the big benefit of the MultiChoice Universal Valve. Once the MultiChoice rough is installed, future shower function upgrades or style changes can easily be made without altering the plumbing behind the wall. 120-degree swing temperature dial. Temperature control includes pre-set safety stop with override. Escutcheon (trim plate) diameter: 7. Designed for use with standard 1/2″ or 3/4″ U.
