Overview

The Shangming brand ZDLM electronic electric high-temperature regulating valve is a 3810L series electric actuator with a servo system inside, which does not require a separate servo amplifier. The electronic control unit is designed in the form of a box and is driven by resin casting. The feedback detection adopts high-performance conductive plastic potentiometer, which is a highly reliable product with 1/250 resolution. The wiring is extremely simple, and only requires a DC4~20mA or DC1~5V input signal AC single-phase power cord to control operation.

Product Overview
Shangming Brand ZDLMElectronic electric high-temperature regulating valveIt is composed of a 3810L series electronic electric actuator and a sleeve regulating valve. The electric actuator has a servo system inside and does not require a separate servo amplifier. The electronic control unit is designed in the form of a box and is driven by resin casting. The feedback detection uses a high-performance conductive plastic potentiometer, which is a highly reliable product with a resolution of 1/250. The wiring is extremely simple, and only a DC4~20mA or DC1~5V input signal AC single-phase power line is needed to control the operation. The electric regulating valve regulating mechanism adopts a balanced valve plug structure, which has the characteristics of good valve stability, low vibration, low noise, low sensitivity to temperature, and allows for large pressure difference. Used in situations with high traffic and low leakage requirements.
