Overview
The Shuangjia valve electric sleeve temperature regulating valve receives DC current signals from the regulating instrument, changes the flow rate of the regulated medium, and maintains the controlled process parameters at the given values. Widely used in the production automation control of industrial sectors such as power, metallurgy, chemical, petroleum, textile, pharmaceutical, papermaking, etc.
Product Details

Shuangjia ValveElectric sleeve temperature regulating valveThe nominal diameter ranges from 20 to 200mm, with nominal pressures of 1.0, 1.6, 4.0, and 6.4MPa. The operating temperature range is from -40 ℃ to 450 ℃, and the received signal is 0~10mA.DC or 4~20mA.DC. The electric single seat temperature regulating valve is suitable for situations with small pressure difference, high medium viscosity, or slight particle impurities. Electric sleeve temperature regulating valve is suitable for situations with large pressure difference. According to the material of the sealing part of the valve, there are two types: metal metal and non-metal metal seals. The latter can achieve a leakage rate of VI level (zero leakage) when the valve is closed. According to the different packing materials, it can be divided into two types: general packing seal and corrugated pipe seal. The former is used in general occasions, while the latter is used in important occasions where leakage is not allowed. The flow characteristics are linear or equal percentage. The electric flow temperature control valve can be divided into two types of actuators: ordinary type and electronic type. A variety of varieties and scales are available for selection.
