Electric control valve in the installation should pay attention to the following aspects: (1) The control valve is field instrument, requiring ambient temperature should be -25 ~ 60 ℃, relative humidity ≤ 95%. If it is installed in the open air or high temperatures, should be taken to water, cooling measures. In a place away from the local oscillator source or increase anti-vibration measures. (2) The control valve should normally be mounted vertically, can be tilted under special circumstances, such as the tilt angle is large or when the valve itself too much weight bearing parts of the valve protection should be increased. (3) installation of the pipe valve is generally not too high off the ground or floor, height greater than 2m in the pipeline should be possible to set platform to facilitate the operator wheel and easy maintenance. (4) control valve piping should be cleaned before installation to remove dirt and weld slag. After installation, to ensure not to impurities left in the valve body, valve should be cleaned again, which leads to media so that all valves should be open, in order to avoid impurities stuck. After using the hand wheel, should be restored to its original neutral position. (5) In order to adjust the valve in the event of failure or repair the case of the production process to continue, bypass line valve should be added. Should also pay particular attention to whether the valve is installed in line with the requirements process. (6) the electrical part of the electric control valve shall be installed according to the construction requirements for electrical equipment. The case of explosion-proof products should be "an explosion hazardous area electrical installation standard" requirements for installation. Such as live wire with SBH-type or other six-core or eight-core, outer diameter of Φ11.3mm around the rubber cable installation. In the use and maintenance, in the explosive power spaces of the explosion-proof surface openings for maintenance and pry play. Do not knock while the removable scratch injury or explosion-proof surface, repair to restore the original after the explosion-proof requirements of the state.

译文：
电动调节阀在安装使用时要注意以下几方面： (1)调节阀属于现场仪表，要求环境温度应在-25～60℃范围，相对湿度≤95%。如果是安装在露天或高温场合，应采取防水、降温措施。在有震源的地方要远离振源或增加防振措施。 (2)调节阀一般应垂直安装，特殊情况下可以倾斜，如倾斜角度很大或者阀本身自重太大时对阀应增加支承件保护。 (3)安装调节阀的管道一般不要离地面或地板太高，在管道高度大于2m时应尽量设置平台，以利于操作手轮和便于进行维修。 (4)调节阀安装前应对管路进行清洗，排除污物和焊渣。安装后，为保证不使杂质残留在阀体内，还应再次对阀门进行清洗，即通入介质时应使所有阀门开启，以免杂质卡住。在使用手轮机构后，应恢复到原来的空档位置。 (5)为了使调节阀在发生故障或维修的情况下使生产过程能继续进行，调节阀应加旁通管路。同时还应特别注意，调节阀的安装位置是否符合工艺过程的要求。 (6)电动调节阀的电气部分安装应根据有关电气设备施工要求进行。如是隔爆型产品应按《爆炸危险场所电气设备安装规范》要求进行安装。如现场导线采用SBH型或其它六芯或八芯、外径为Φ11.3mm左右的胶皮安装电缆线。在使用维修中，在易爆场所严禁通电开盖维修和对隔爆面进行撬打。同时在拆装中不要磕伤或划伤隔爆面，检修后要还原成原来的隔爆要求状态。
