德国费斯托FESTO标准气缸

FESTO紧凑性能电磁阀选型首先应该依次遵循安全性，可靠性，适用性，经济性四大原则，其次是根据六个方面的现场工况（即管道参数、流体参数、压力参数、电气参数、动作方式、特殊要求进行选择）。选型依据-
一、根据管道参数选择电磁阀的-通径规格（即DN）、接口方式
1、按照现场管道内径尺寸或流量要求来确定通径（DN）尺寸。
2、接口方式，一般>DN50要选择法兰接口，≤DN50则可根据用户需要自由选择。

二、根据流体参数选择电磁阀的-材质、温度组
1、腐蚀性流体-宜选用耐腐蚀电磁阀和全不锈钢；食用超净流体-宜选用食品级不锈钢材质电磁阀。
2、高温流体-要选择采用耐高温的电工材料和密封材料制造的电磁阀，而且要选择活塞式结构类型的。FESTO紧凑性能电磁阀的工作原理和热动力式疏水阀相同，它在热动力式疏水阀的汽室外面增加一层外壳。外壳内室和蒸汽管道相通，利用管道自身蒸汽对疏水阀的主汽室进行保温。使主汽室的温度不易降温，保持汽压，疏水阀紧紧关闭。当管线产生凝结水，疏水阀外壳降温，疏水阀开始排水；在过热蒸汽管线上如果没有凝结水产生，疏水阀不会开启，工作质量高。阀体为合金钢，阀心为硬质合金，该阀zui高允许温度为550℃，经久耐用，使用寿命长，是高压、高温过热蒸汽疏水阀。
