1、安装高压针阀前，检查针阀外形有否损坏，若有损坏将可能导致针阀不能正常使用，此时可向技术人员或者供应商咨询。
1 、 before installing high pressure needle valve, check whether the needle valve is damaged or not. If damaged, it may cause the needle valve not to be used properly, and then consult with the technician or supplier.
2、安装前，检查阀接口、阀内部以及阀表面是否干净，如果不干净的话，可以用气枪吹扫（注意：如果有铁屑之类的，务必先将铁屑等固体颗粒倾倒出来再吹扫，以免损伤阀体内部甚密封面）。
2, before installation, check valve, valve and valve interface internal surface is clean, if not clean, can be used for blowing gun (Note: if there is iron like, be sure to scrap iron and other solid particles poured out to purge the body even, so as not to damage the sealing surface).
3、按照针阀结构，正确安装针阀于管路或系统上。对于进出口有标识的针阀，按照标识连接。对于进出口没有标识的针阀，按照“低进高出”的原则连接，即处于低位的连接口是进口，处于高位的连接口是出口。注意管路和系统也须是清洁的，并且系统中应安装有过滤器以保护系统元器件。
3, according to the needle valve structure, correctly install the needle valve in the pipeline or system. For the import and export of needle valves marked, according to the identification link. For the import and export of the needle valve does not identify, in accordance with the "low into higher out" principle of connection, that is, the low level of the mouth is imported, the high level of the mouth is the exit. Note that piping and systems must also be clean and that filters should be installed in the system to protect system components.
4、安装完毕后，启/闭针阀2-3次，以检查其性能是否良好。注意，开启或关闭阀门时，忌用力过猛，用力过猛可能会造成螺纹滑丝，甚关闭时易造成密封失效。通常我们关闭阀门时，只要能关闭并耐住系统压力即可，不能强蛮旋转手柄。
4 after installation, open or close the needle valve 2-3 times to check its performance is good. Note that when opening or closing the valve, avoid excessive force, excessive force may lead to thread sliding, and even closed when it is easy to cause sealing failure. Usually when we close the valve, as long as it can close and withstand the pressure of the system, it can not be strongly rotating handle.
