检查气动阀门的型号，参数是否符合现场安装需要和技术要求。
Check whether the model and parameters of the pneumatic valve meet the on-site installation requirements and technical requirements.
检查气动阀门的气缸、位置指示器，确保无损伤。
Check the cylinder and position indicator of the pneumatic valve to ensure there is no damage.
必须把气动阀的管道清洗、吹扫干净；如介质内有杂质，在阀前管道上应加装过滤阀。
The pipeline of the pneumatic valve must be cleaned and blown clean; If there are impurities in the medium, a filter valve should be installed on the pipeline in front of the valve.
按气动阀阀体上箭头指示的方向安装（顺流安装）把气动阀门的接口与管道连接上，并确保连接处良好的密封。
Install in the direction indicated by the arrow on the pneumatic valve body (downstream installation), connect the interface of the pneumatic valve to the pipeline, and ensure good sealing at the connection.
如加装电磁阀，注意连接处确保密封良好。
If installing an electromagnetic valve, pay attention to ensuring that the connection is securely sealed.
需要焊接连接时，避免高温传到气动阀的填料等处。
When welding connections are required, avoid high temperatures from being transmitted to the packing of the pneumatic valve.
气动阀安装及加装电磁阀注意事项
Precautions for installing pneumatic valves and adding solenoid valves
必须保证流体、气源洁净，以防堵塞电磁阀或气缸活塞。
It is necessary to ensure that the fluid and gas source are clean to prevent blockage of the solenoid valve or cylinder piston.
电磁阀的线圈带电正常工作时发热较高，请勿触摸。
When the coil of the solenoid valve is charged and operates normally, it generates high heat. Please do not touch it.
电磁阀的线圈带电时，禁止取下，以防止触电。
When the coil of the solenoid valve is energized, it is prohibited to remove it to prevent electric shock.
电磁阀的线圈、插座、电磁管及连接部分，严禁击打碰撞，以免损坏。
The coil, socket, electromagnetic tube, and connecting parts of the solenoid valve are strictly prohibited from being hit or collided to avoid damage.
电磁阀的线圈带电时，严禁覆盖，以防过热烧毁。
When the coil of the solenoid valve is energized, it is strictly prohibited to cover it to prevent overheating and burning.
电磁阀的实际电源电压不能超出公差范围。
The actual power supply voltage of the solenoid valve cannot exceed the tolerance range.
介质工作压力，工作温度、黏度，不得超出规定的范围。
The working pressure, working temperature, and viscosity of the medium must not exceed the specified range.
