Overview

The explosion-proof electric single seat regulating valve 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 requires a DC4~20mA or DC1~5V input signal AC single-phase power line to control operation. The electric regulating valve regulating mechanism adopts a balanced valve plug structure with good valve stability,

Product Details

，Explosion proof electric single seat regulating valveThe Shangming brand ZDLM electronic electric high temperature regulating valve is composed of a 3810L series electronic electric actuator and a sleeve regulating valve. The electric actuator has 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 uses a 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 line to control 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.
