TVH.4201 – 3/4″ Thermostatic Valve

Supply Stops – There are two safety stops at each water inlet to prevent water flow in case of installation and repairs.

Handle Operation – The handle is used to control the temperature of water flowing through the outlet. This handle does not control the volume of water flowing through the valve.
As the valve is installed, care should be taken to maintain a proper distance from the back of the valve to the surface of the finished tile which should be between 2.77” and 3.44”. Also, the valve must be installed vertically and not at an angle. In case, a tile is thicker or the wall is deep, extensions are used for elongating both handles of the valve to ensure proper setting of the trim (length of extensions for TVH.4201 valve is 1.40”). Extension kits comprise of thermostatic handle extension, which can be ordered separately in chrome, brushed nickel, or other special finishes.

Cut Out Dimensions – The cut out in the wall should be 4.44” X 4.44” which is properly covered by the trim plate. This will ensure that the trim plate will cover the cut out hole in the wall.

Trims – The trims comprise of the well-finished trim plate and handle. The trim plate is used to cover the wall and has markings for HOT/COLD for the temperature control handle. Over the temperature control knob, is an anti-scald temperature stop ring which is a safety feature in this thermostatic value. With the help of this ring, the temperature of the water is regulated. Covering this ring is the handle knob which has a push-button on the side. To adjust the water temperature, one needs to press this button and move the handle in a hot or cold direction. Without pressing it, the user will not be able to rotate the handle to the full HOT position – as an anti-scald prevention mechanism. The anti-scald temperature stop ring should be fitted tightly over the valve (tapping using a rubber mallet might be required during installation) for it to function properly. Depending upon the shower model, trims can be of different shapes and sizes, varying from square to circular shower handles.
