自力式铸钢温度调节阀DN50 YZW ZZWP

Application of Self operated Temperature Control Valve:
Widely used for automatic temperature regulation in heating, air conditioning, domestic hot water, as well as in special occasions such as chemical, textile, pharmaceutical and other production processes.

Principle of self operated temperature control valve:

The self operated temperature control valve utilizes the principle of liquid thermal expansion and incompressibility to achieve automatic adjustment. The liquid expansion inside the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the volume of the temperature sensing liquid inside the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature liquid expands, pushing the valve core downwards to close the valve and reduce the flow rate of the heat medium; When the temperature of the controlled medium is lower than the set value, the temperature sensing liquid contracts, and the reset spring pushes the valve core to open, increasing the flow rate of the heat medium.

Characteristics of self operated temperature control valve:
1. Small size, light weight, and easy installation;
2. Accurate, reliable, and long-lasting;
3. Maintenance free work;
4. Easy to adjust settings;
5. Passive operation (no power supply, normal operation of gas source);
6. No need for expensive debugging costs;
7. The valve body seal adopts a V-shaped high-temperature sealing component to prevent the possibility of the valve stem being too tight or leaking.
