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 when the reverse, so that both fluid along the direction of movement of spool when closed, the flow control valve capacity will be increased.
选择调节阀，首先要计算流通能力的大小。
To select flow regulating valve, the flow capacity must be calculated first.
因而阀流通能力比一般调节阀大且无泄漏，在许用压差范围内可作切断阀用。
Thus the valve control valve flow capacity than the average large and no leakage in the range of allowable pressure shut-off valve can be used.
