1·As important directional control valve, direction valve is used to control the direction of movement part.

换向阀作为重要的方向控制阀，用来实现运动部件的方向控制。

2·When a set of Hydraulic Elevators are used, then a hydraulic supply from a directional control valve is required.

当使用一套液压提升集时，那么一个提供液压动力的方向控制阀是必需的。

3·In pneumatic position servo system with proportional directional control valve and control cylinder, the centre adjust emt voltage is one of the important factors that influence control precision.

在比例方向阀控缸气动位置伺服系统中，置中电压是影响控制精度的重要因素之一。

4·An integral electronic board, mounted to the side of the valve, may be utilized to control the 4-way directional valve and motor direction (when not using a rotary encoder control).

安装在计量阀侧边的集成电板可用于控制该独特的4通阀门和马达方向（在不使用旋转编码控制器时）。

5·So in effect the proportional directional valve is acting as both a directional valve and a flow control valve.

于是在实际上比例阀可以同时作为方向阀和流量阀来使用。

6·The utility model discloses a pneumatic control multi-way directional valve applied to a remote pneumatic-control hydraulic system with the coexistence of large flow rate and small flow rate.

一种应用于远程气动控制液压系统的大、小流量并存的多气控换向阀。
