檢查氣動閥門的型號，參數是否符合現場安裝需要和技術要求。
Check whether the model and parameters of the pneumatic valve meet the on-site installation requirements and technical requirements.
檢查氣動閥門的氣缸、位置指示器，確保無損傷。
Check the cylinder and position indicator of the pneumatic valve to ensure there is no damage.
必須把氣動閥的管道清洗、吹掃干凈；如介質內有雜質，在閥前管道上應加裝過濾閥。
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.
按氣動閥閥體上箭頭指示的方向安裝（順流安裝）把氣動閥門的接口與管道連接上，并確保連接處良好的密封。
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.
如加裝電磁閥，注意連接處確保密封良好。
If installing an electromagnetic valve, pay attention to ensuring that the connection is securely sealed.
需要焊接連接時，避免高溫傳到氣動閥的填料等處。
When welding connections are required, avoid high temperatures from being transmitted to the packing of the pneumatic valve.
氣動閥安裝及加裝電磁閥注意事項
Precautions for installing pneumatic valves and adding solenoid valves
必須保證流體、氣源潔凈，以防堵塞電磁閥或氣缸活塞。
It is necessary to ensure that the fluid and gas source are clean to prevent blockage of the solenoid valve or cylinder piston.
電磁閥的線圈帶電正常工作時發熱較高，請勿觸摸。
When the coil of the solenoid valve is charged and operates normally, it generates high heat. Please do not touch it.
電磁閥的線圈帶電時，禁止取下，以防止觸電。
When the coil of the solenoid valve is energized, it is prohibited to remove it to prevent electric shock.
電磁閥的線圈、插座、電磁管及連接部分，嚴禁擊打碰撞，以免損壞。
The coil, socket, electromagnetic tube, and connecting parts of the solenoid valve are strictly prohibited from being hit or collided to avoid damage.
電磁閥的線圈帶電時，嚴禁覆蓋，以防過熱燒毀。
When the coil of the solenoid valve is energized, it is strictly prohibited to cover it to prevent overheating and burning.
電磁閥的實際電源電壓不能超出公差范圍。
The actual power supply voltage of the solenoid valve cannot exceed the tolerance range.
介質工作壓力，工作溫度、黏度，不得超出規定的范圍。
The working pressure, working temperature, and viscosity of the medium must not exceed the specified range.
