SQD202 Top Guide Sleeve Control Valve

SQD202 type electric sleeve regulating valve adopts sleeve guide, pressure balance type double sealing surface, single sealing surface structure, is a force balance type regulating valve, the valve body structure is compact, the fluid channel is S streamlined, the advantage is small pressure drop loss, large circulation, wide adjustable range, high precision flow characteristics. The control valve is equipped with a small, sturdy and high-precision actuator that receives ON-OFF or 4~20mADC or 1~5V DC signals for proportional action. It is more suitable for use under the conditions of good dynamic stability, low noise, cavitation flash evaporation, high and low temperature and high pressure differential fluid control.
