ZDLN type electric double seated control valve adopts double guide structure, compact valve body structure, S streamlined fluid channel, small pressure drop loss, large flow volume, wide adjustable range and high flow characteristic accuracy. Due to the guidance on the top and bottom of the valve plug, it has the characteristics of shock resistance and wear resistance. The control valve is equipped with a multi-spring type membrane actuator, which has a small structure and a large output force. It is more suitable for the process conditions that require good stability, high reliability, high pressure, high pressure difference, and the fluid medium contains slurry and is easy to block and good control
