The ESBE Thermic valves type TV are designed to
ensure optimum operating temperature inside a boiler. The thermostat
within a TV valve allows flow through the bypass until the desired
temperature is reached. TV valves can be mounted on either supply
or return pipes.
When the temperature inside the boiler reaches 160°F (72°C),
the thermic TV valve will allow flow of hot water directly into
the system or indirect heater. Between 160°F and 170°F,
the TV valve allows the supply flow to bypass and mix with the
return water, keeping the operating temperature levels high.
At approximately 180°F (82°C) most of the flow is directed
into the system.
Thermic valve TV will allow full bypass until the return flow
temperature rises to 140°F (60°C). The TV valve opens
when a 140°F minimum return temperature is reached. At approximately
158°F (70°C) most of the flow will be through the system.
An adjustable balancing valve (or ball valve) must be installed
on the bypass. With the bypass fully open, allow the temperature
levels inside the boiler to reach standard operating level.
Note, the bypass balancing valve should be adjusted (throttled)
if the hot water flow is not automatically directed into the
system, otherwise no adjustment is required.
