Product overview

The biggest feature of the valve is that it only needs ordinary 220V power supply, and uses the energy of the regulated medium to directly automatically adjust and control the temperature of steam, hot gas, hot oil and gas. It can also be used to prevent overheating or heat exchange. The valve has the advantages of simple structure, convenient operation, wide temperature regulation range, fast response time, reliable sealing performance, and can be adjusted at will during operation, Therefore, it is widely used in hot water supply in chemical industry, petroleum, food, textile, hotels and restaurants.

Product features

The nominal diameter of this series of products is from 20 to 200mm, the nominal pressure is 1.0, 1.6, 4.0 and 6.4Mpa, the service temperature range is - 20 ℃ ~ 350 ℃, and the received signal is 0 ~ 10ma.dc or 4 ~ 20ma.dc to change the regulated medium flow and keep the controlled process parameters at the given value. The single seat regulating type is suitable for occasions with small differential pressure, large medium viscosity or slight particle impurities. The sleeve adjustment type is suitable for occasions with large pressure difference.
