ZDLM electric sleeve regulating valve | electronic electric steam regulating valve
1、 Electric sleeve regulating valve overview
ZDLMElectric sleeve regulating valveAdopting a sleeve guided, pressure balanced double sealing surface valve core structure, equipped withPSL、3810Electronic electric actuator. The flow channel isSStreamlined, it has the characteristics of smooth operation, large allowable pressure difference, accurate flow characteristics, and low noise. Electric sleeve regulating valves are particularly suitable for working environments with high flow rates, large pressure differences before and after the valve, and low leakage requirements.
