FESTO电磁阀在选择时要考虑的因素资料有哪些
一：FESTO电磁阀适用性　　管路中的流体必须和选用的电磁阀系列型号中标定的介质一致电磁阀。流体的温度必须小于选用电磁阀的标定温度。电磁阀允许液体粘度一般在20CST以下，大于20CST应注明。工作压差，管路压差在小于0.04MPa时应选用如ZS,2W,ZQDF,ZCM系列等直动式和分步直动式；低工作压差大于0.04MPa时可选用先导式（压差式）电磁阀；工作压差应小于电磁阀的标定压力；一般电磁阀都是单向工作，因此要注意是否有反压差，如有安装止回阀。流体清洁度不高时应在电磁阀前安诺和阀门装过滤器，一般电磁阀对介质要求清洁度要好。注意流量孔径和接管口径；电磁阀一般只有开关两位控制；条件允许请安装旁路管，便于维修；有水锤现象时要定制电磁阀的开闭时间调节。注意环境温度对电磁阀的影响。电源电流和消耗功率应根据输出容量选取，电源电压一般允许±10%左右，必须注意交流起动时VA值较高。
二、FESTO电磁阀可靠性电磁阀分为常闭和常开二种；一般选用常闭型，通电打开，断电关闭；但在开启时间很长关闭时很短时要选用常开型了。寿命试验，工厂一般属于型式试验项目，确切地说还没有电磁阀的专业标准，因此选用电磁阀时慎重。动作时间很短频率较高时一般选取直动式，大口径选用快速系列。
三、FESTO电磁阀安全性　　一般电磁阀不防水，在条件不诺和阀门允许时请选用防水型，工厂可以定做。电磁阀的标定公称压力一定要超过管路内的压力，否则使用寿命会缩短或产生其它意外情况。有腐蚀性液体的应选用全不锈钢型，强腐蚀性流体宜选用塑料王电磁阀。爆炸性环境必须选用相应的防爆产品。
四、经济性　　有很多电磁阀可以通用，但在能满足以上三点的基础上应选用经济的产品电磁阀在选择时要考虑的因素。
译文：A: applicability fluid pipe must be consistent in the medium of electromagnetic valve calibration and the electromagnetic valve series models in the. The temperature of the fluid must be less than the calibration temperature of the solenoid valve. Solenoid valve to allow the liquid viscosity generally below 20CST, more than 20CST should be specified. Working pressure, the maximum pressure in the pipeline is less than 0.04MPa should be used such as ZS, 2W, ZQDF, ZCM series direct drive type and step and direct action; minimum working pressure is more than 0.04MPa can be selected for the pilot (differential) electromagnetic valve; the maximum working pressure should be less than the maximum nominal pressure solenoid valve; general solenoid valve is a one-way operation, so should pay attention to whether the anti pressure, if installed check valve. Fluid cleanliness is not high when filter before the solenoid valve anno and valve, the general cleanliness requirements solenoid valve on the media. Note flow pore diameter and over; solenoid valve generally only two control switches; conditions permit to install a bypass pipe, easy to repair; a water hammer phenomenon to customize the opening and closing time adjustment of electromagnetic valve. Pay attention to the influence of environmental temperature on the solenoid valve. Power supply current and power consumption should be selected according to the output capacity, power supply voltage generally allows ± 10%, attention must be paid to the exchange value of the higher VA start. Two, reliability Electromagnetic valve is normally closed and normally open two; general selection of normally closed, open, power off; but in the open for a long time close very short to use normal open type. Life test, factory type test items are generally, exactly professional standard Chinese no electromagnetic valve, so use caution when solenoid valve manufacturers. Action time is very short high frequency selecting direct acting, rapid series of large caliber selection. Three, security General solenoid valve is not waterproof, in the condition of no and valve allows to use water when you type, the factory can be customized. The maximum calibration nominal pressure solenoid valve must be more than the maximum pressure within the pipe, otherwise life will be shortened or have other unforeseen circumstances. Corrosive liquids should be used all stainless steel type, strong corrosive fluids should use plastic Wang solenoid valve. Explosive environment must use the appropriate explosion-proof products. Four, economic There are a lot of solenoid valve can be generic, but in the foundation to meet the above three points should choose the most economical products..
