Self Operated Flow Temperature Control Valve

The working principle of self-operated flow temperature control valve is based on the law of thermodynamics, and the opening degree of the valve is controlled by the temperature and pressure of the fluid. When the temperature or pressure of the fluid changes, the position of the valve will be automatically adjusted to keep the flow and temperature of the fluid within the set range.
