Product details

ZZWPE温度自力式[电动型]调节阀(图1)

Product Description:

Self operated electric control temperature regulating valve (suitable for larger diameters and heat transfer oil control), the biggest feature of this valve is that it only requires a regular 220V power supply, and uses the energy of the regulated medium to directly adjust and control the temperature of steam, hot gas, hot oil and gas media. It can also be used to prevent overheating or heat exchange. The valve has a simple structure, easy operation, wide temperature control range, fast response time, reliable sealing performance, and can be adjusted freely during operation. Therefore, it is widely used in hot water supply in chemical, petroleum, food, textile, hotel and restaurant departments.

Product features:

The nominal diameter of this series of products ranges from 20 to 200mm, with nominal pressures of 1.0, 1.6, 4.0, and 6.4MPa. The operating temperature range is from -20 ℃ to 350 ℃, and the received signal is from 0 to 10mA DC or 4-20mA DC is used to change the flow rate of the regulated medium to maintain the controlled process parameters at the given values. The single seat regulating type is suitable for situations where the pressure difference is small, the medium viscosity is high, or there are slight particle impurities. The sleeve adjustment type is suitable for situations with large pressure differences.
