By varying the current to either solenoid, the amount of spool movement can be varied and hence the amount of flow through the valve can be controlled.
通过改变两个之一电磁铁的电流，阀芯移动的位移能够被改变，因此控制了通过阀的流量。
When the control valve when the reverse, so that both fluid along the direction of movement of spool when closed, the flow control valve capacity will be increased.
当调节阀反向使用时，既流体沿着使阀芯关闭的方向流动时，调节阀的流通能力会增大。
To improve the response speed of on-off solenoid valve of big flux, detailed analysis on poppet valve is given and an on-off solenoid valve with movement of both spool and cover is designed.
通过对锥阀特性的分析，设计了一种阀芯、阀套同时运动的芯套双动高速开关阀，该阀增大了高速开关阀的开口度，提高了响应速度和流量。
