Temperature controllers
Direct-acting temperature controllers perform flow control without the need for electrical or pneumatic power supply depending on the temperature.
Choosing the valve size
Hydraulic temperature regulators are direct-acting regulators that do not require the use of electrical energy for their operation.
The force generated by the expanding liquid that fills the drive-controller-sensor system is used as the driving force.
Direct-acting temperature controllers are used to maintain a set temperature in pipelines and tanks, etc.
Compared with electronic direct–acting temperature controllers, they do not have high speed - their inertia, that is, the delay in operation after a change in the temperature of the controlled medium, averages 20-50 C.
| Hydraulically controlled temperature controls. | Direct-acting temperature controllers consist of a control valve and a thermostatic element with a thermal sensor (thermoball). The thermal sensor is connected to the thermoelectric element by a capillary tube from 1 to 5 m |
They are used in heating, ventilation, shipbuilding, water supply, etc.
