Products Details

ZZWPE temperature self operated [electronic] control valve

It can also be used in the occasion of preventing overheating or heat exchange. The valve has simple structure, convenient operation, wide range of temperature regulation and wide range of temperature control It is widely used in the hot water supply of chemical industry, petroleum, food, textile, hotels and restaurants.


Product features:
The nominal diameter of this series of products is from 20 to 200 mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4 MPa, the temperature range is - 20 ℃ ~ 350 ℃, and the receiving signal is 0 ~ 10 mA.DC or 4 ~ 20 MA.DC to change the flow rate of the regulated medium, so as to keep the controlled process parameters at the given value. The single seat regulating type is suitable for the occasions with small pressure difference, large medium viscosity or slight particle impurities. The sleeve adjustment type is suitable for the occasions with large pressure difference.
