7) speed control valve may be slightly leaked, it is difficult to vulgar control of the cylinder.
At the same time, the speed control valve shall not be used as a stop valve.
8) should be installed as close as possible to the cylinder to improve the control performance. 
同时，不得把速度控制阀当做截止阀使用。
8）应尽量靠近气缸安装，以提高控制，否则，响应时间过长，气缸速度有可能难于控制。
当气缸速度控制阀之间的配管容积大于气缸容积时，就很难控制气缸速度。
也说明气缸缸径越小，速度控制越难。
Otherwise, the response time is too long and the cylinder speed may be difficult to control.
When the pipe volume between the cylinder and the speed control 
valve is larger than the cylinder volume, it is difficult to control the cylinder speed.
Also shows that the smaller the cylinder bore, the more difficult the speed control.
4）顺时针旋转调节手轮，节流阀是逐渐关闭的。
使用时，应从全闭状态逐渐打开，将气缸调要求的速度。
5）速度控制阀的调节圈数不得超过给定值，以免损坏针阀。
4) clockwise rotation adjustment hand wheel, throttle valve is gradually closed.
When used, should be fully closed from the state to open, 
the cylinder transferred to the required speed.
5) The number of adjustment points of the speed control 
valve shall not exceed the given value, so as not to damage the needle valve.
6) universal speed control valve, should not be used for frequent rotation of the situation

When installing, piping should be blown in advance, make sure that the flow of the valve is not reversed.
2) joint thread screwed on the hand, with the tool and then spin 2 to 3 laps, the installation torque to be appropriate.
3) pipe joints on the thread, generally have been coated with sealant, usually can be used 2 to 3 times.
If the thread is too tight, the sealant will be squeezed out and should be removed.
万向式速度控制阀，不宜用于经常回转的情况
7）速度控制阀可能存在微漏，难于对气缸进行低俗控制。
