Product Overview：
The ZDLM electric sleeve control valve adopts sleeve guide, pressure balanced double sealing surface and single sealing surface structure. It is a force balanced control valve.Control valve is equipped with on-off or 4-20mADC or 1-5V DC signal for proportional action of small, firm and high precision actuator more suitable for dynamic stability, low noise, cavitation/flash.high and low temperature, high pressure difference fluid control conditions.
