Thermostatic Mixing Valves

Thermostatic mixing valves precisely mix hot and cold water to a pre-selected temperature. TMV’s are primarily installed in health care facilities, hospitals and nursing homes to prevent scalding. The valves operate using a thermostatic element and sensor set.

In order to safeguard against a valve failure  design includes a thermal shut down component which prevents scalding in the event of a valve failure. To reduce the possibility of failure during operation, these valves require servicing on a regular basis.  We can implement a regular servicing schedule and submit a commissioning/maintenance reports upon completion.
