Mixing valve for back to back installation

摘要

The invention pertains to improved single handle mixing valves suitable for use in back to back installations, as for example tub/shower valves in an apartment building or hotel. In such installations it is important to provide for proper orientation of valve water mix control parts so as to prevent the water mix from being uncomfortably or dangerously hot in the initial phase of valve opening. The invention provides structure and arrangement such that proper orientation can be achieved by a simple re-orientation or reversal of a part or parts exteriorly of the valve body.
