Other Control Valves
The self-operated temperature control valve uses the principle of liquid thermal expansion to achieve automatic adjustment without an auxiliary actuator. The liquid in the temperature sensor expands uniformly. This valve controls the medium's temperature by expanding or contracting the temperature-sensitive liquid in the sensor, thus adjusting the valve opening. When the medium's temperature exceeds the set value, the liquid expands, pushing the spool down to close the valve and reduce thermal media flow. When the temperature falls below the set value, the liquid contracts, and the reset spring pushes the spool to open, increasing the flow. This valve is used in heating, air conditioning, domestic hot water, petrochemical, electric power, textile, rubber, food, and other industries.
The pressure reducing valve is designed for parallel water supply systems serving both firefighting and domestic needs. In the event of a fire, it prioritizes water flow to firefighting efforts by automatically cutting off the domestic supply, ensuring adequate water for emergency response. Once firefighting operations cease and water pressure stabilizes, the valve reopens to restore the domestic supply. This mechanism eliminates the need for a separate dedicated firefighting water pipeline, significantly reducing construction costs and water usage. Ideal for integrated water management, this valve ensures efficient and reliable water distribution in critical situations.
