Electric Actuated Double Seated Globe Control Valve

Electric Actuated Double Seated Globe Control Valve

Theelectric double seated control valveconsists of the PSL series and the 3810L series of electronic actuators anddouble seated globe valve.The power supply ofelectric double seated globe valve为220V.AC 50Hz，包含伺服放大器，位置信号发生器，位置限制开关和阀位置显示。双座位地球阀可以直接接受4-20MADC或1-5VDC的输入信号，以控制阀门的打开，以实现调节介质的压力流量和温度的目的。同时，可以输出（4-20MADC或1-5VDC）位置反馈信号。

The electric double seated globe valve has two upper and lower valve plugs. The thrust of the fluid acting on the upper and lower valve plugs is opposite in direction and close in force.The unbalanced force is small, the allowed differential pressure is large, and the rated flow coefficient is larger than that of single-seated globe valve,but the leakage is larger. It is suitable for clean media where the leakage requirement is not strict and the pressure difference between the upstream and the downstream is large.

The Features of Electric Double Seated Control Valve:

1. Double-guided electric double seated globe valve with good stability during operation.
2. There are two valve plugs and valve seats. The “four-way” valve body can be easily changed from forward installation to reverse installation without the need to re-select the positive or reaction type of the actuator.
3. Large flow coefficient: Compared with other control valves of the same diameter, the double seated globe valve can flow more fluids. Therefore, in order to obtain the same flow coefficient, the electric double seated control valve can be selected with a smaller thrust of electric actuator.
4. The adjustable range is large, the inherent adjustable ratio is 50, and the flow characteristics have linear and equal percentages.
5. Electric actuators come in many forms and can be used for 4~20mA.DC or 0~10mA.DC.
6.Theelectric double seated globe control valveis suitable for clean media where the leakage requirement is not strict and the pressure difference between the upstream and the downstream is large.
