Check whether the model and parameters of the pneumatic valve meet the 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 air 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 pneumatic valve must be cleaned and purged; 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 with the pipeline, and ensure that the connection is well sealed.

如加裝電磁閥，注意連接處確保密封良好。

If a solenoid valve is added, pay attention to ensure that the connection is well sealed.

需要焊接連接時，避免高溫傳到氣動閥的填料等處。

When welding connection is required, avoid high temperature being transmitted to the packing of pneumatic valve.

2、 Precautions for installing pneumatic valve and adding solenoid valve

必須保證流體、氣源潔凈，以防堵塞電磁閥或氣缸活塞。

The fluid and air source must be clean to prevent blocking the solenoid valve or cylinder piston.

電磁閥的線圈帶電正常工作時發(fā)熱較高，請勿觸摸。

Do not touch the coil of the solenoid valve, which has high heat when it is electrified and works normally.

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 forbidden 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, solenoid pipe and connection part of the solenoid valve shall not be 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 solenoid valve is electrified, it is forbidden 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 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(guī)定的范圍。

The working pressure, temperature and viscosity of the medium shall not exceed the specified range.
