the direction control valve 方向控制阀
Wherein the control pressure is called pressure control valve to control the flow of known flow control valve to control flow through ﹑ called off and the direction control valve.
其中控制压力的称为压力控制阀，控制流量的称为流量控制球阀，控制通﹑断和流向的称为方向控制球阀。
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。
When the control valve to change flow direction, due to changes in flow path will cause changes in value.
当调节阀改变流动方向时，由于流路的变化会引起值变化。
