1Electric control valve manufacturerProduct Overview:
The nominal diameter of the electric flow regulating valve 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 regulating valve is suitable for situations with small pressure difference, high medium viscosity, or slight particle impurities. Electric sleeve 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 of seals: metal metal and non-metal metal seals. 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 control valve can be divided into two types of actuators: ordinary and electronic.
