Overview
Technical parameters: The ZDLM electric precision sleeve 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 production automation control of industrial sectors such as power, metallurgy, chemical, petroleum and textile, pharmaceuticals, and papermaking. The valve product adopts thin film steam automatic drive, and the compact sleeve electric single seat regulating valve is suitable for situations with large pressure difference and leakage.
Product Details
ZDLM electric precision sleeve regulating valveAccept the DC current signal from the regulating instrument, change the flow rate of the regulated medium, and maintain the controlled process parameters at the given values. Widely used in production automation control of industrial sectors such as power, metallurgy, chemical, petroleum and textile, pharmaceuticals, and papermaking. The nominal diameter of this series of products ranges from 20 to 300mm, with nominal pressures of 1.6, 4.0, and 6.4MPa. The received signal is 0-10mA.DC or 4-20mA.DC, and the operating temperature range is from -40 ℃ to 450 ℃. 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 and leakage.
