overview

The ZDLM electronic electric 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.

This series of products has a nominal diameter of 20-300mm, nominal pressures of 1.6, 4.0, and 6.4 MPa, and can receive signals from 0-10mA. DC or 4-20mA. DC. The range of turbidity used is from -40 ℃ to 450 ℃. Electric sleeve regulating valve is suitable for situations with large pressure difference and leakage.
