Temperature control valves

Self-operated temperature control valves follow the process temperature after the valve, and they control the opened and closed positions of the valve depending on the proximity of the temperature to the set value.

ARI self-operated temperature control valves are suitable for water, steam and thermal oil.

For heating and cooling

The temperature control valve itself consists of the valve, the capillary pipe and the temperature sensor. The temperature sensor will be installed in the location where the temperature should be monitored. If the temperature exceeds the set value or drop below the set value, the temperature sensor controls the opening or the closing of the valve. This occurs with the help of the liquid present in the capillary tube that either expands or contracts due to the effect of the heat.

Self-operated temperature control valves can be applied for both heating and cooling.
