Two design strategies that three-wayvalvecontrol unsymmetrical cylinder and four way valve control symmetrical cylinder were analyzed from principle and system structure aspects.
The dynamic response performance of the three-way solenoid valve can be effectively improved with the optimization control of the driving parameters adopted.
对驱动参数进行优化控制后，三通电磁阀的动态响应性能得到了大幅度的提高。

Relay valves convert a sustained air flow from a three-way pilot valve into a momentary pulse or bleed, which shifts a control valve and then closes.
