The Dalian Lidi temperature control valve is a self-actuated control valve that does not require external energy. It controls the temperature by adjusting the set point. When the temperature rises, the valve closes proportionally according to the temperature change. The temperature control valve consists of a control valve and a thermostat, which can be applied by selecting different temperature states. The temperature control valve operates based on the liquid expansion principle. If the temperature on the sensor rises, it will heat and expand the liquid filling simultaneously. Under the action of the working piston, the valve closes, and then it cools down...
