Thermostatic Valves
Thermostatic Mixing Valves, sometimes called Tempering Valves, are valves
that prevent scalding or thermal shock by controlling the temperature of the
hot water passing through them.
These valves are often used in nursing homes or nursery schools where the very young or elderly may be at risk.
They are different from pressure-balancing valves because those are controlled by water pressure, while these are thermostatically controlled, which makes them more accurate and allows a steady flow of water. They can be used anywhere that preset water temperature is required.
These valves can be preset to any temperature between 60 degrees F and 120
degrees F with flow rates between .5 gpm and 10 gpm.
Keidel carries the Watts MMV series that use a double throttling design to control both the hot
and cold water supply to the mixed outlet. This enables controlling the temperature to within plus or minus 3 degrees. It also incorporates check valves in both the hot and cold inlets to protect against cross flow.
These valves are available in ½" to 1" sizes in IPS threaded union or CTS sweat union connections.
They can be installed on the hot water supply to any sink, lavatory, tub or shower where temperature control is required.
