The temperature control valve is used at the end of the heating and air-conditioning system to switch flow. The temperature control valve can automatically maintain the indoor temperature of its installation area according to the setting of the thermostat controller. The flexible joint hydraulic sealing method of this series of temperature control valves is innovative, and the connection with the radiator does not require other sealing materials. The rubber sealing ring on the flexible joint can ensure fast, reliable, and multiple installations. The thermostat has an actual temperature display panel for easy adjustment.

The thermostat controller is composed of a bellows filled with special temperature-sensitive liquid; the balance between the temperature-sensitive liquid and saturated gas makes the controller adjust proportionally according to the air temperature. When the indoor temperature rises, part of the temperature-sensitive liquid inside the bellows is converted into gas, causing the bellows to expand and push the valve stem to proportionally close the valve. When the indoor temperature drops, the bellows is contracted by the tension of the spring, and the valve stem opens up proportionally to the valve.
