Thermostatic mixing valve

TVM-H

Description		TVM-H limits and maintains constant Ievel of
		mixing temperature in heating applications.
		The thermostatic mixing valve ensures a
		constant temperature of the mixed water at the
		outlet.
		Advantages
		• Constant temperature of the water at the
		outlet
		• Variable setting of the nominal temperature
		range: 30 … 70 °C
		• Special design with anti-scalding coating
		• System components: accessories and spare
		parts
		Standard design
		A thermostatic cartridge and a return spring
		ensure the constant blend temperature at the
		outlet.
		Thanks to the design of the mixing valve, the
		thermostatic cartridge can be easily replaced in
		the installed valve if the performance decreases,
		which occurs due to normal wear and tear.

Application

Note for fig. 1:

Danfoss PACK solution consists of thermostatic mixing valve TVM-H, motorised valve and programable thermostat.

This solution gives excellent temperature control for the under floor heating system up 200 m2 (TVM-H DN 25) .
