parker电磁阀phs520sx-8-24v-dl-fl货期短 parker派克电磁阀用电磁控的工业设备，是用来控制流体的自动化基础元件，属于执行器，并不限于液压、气动。用在工业控制系统中调整介质的方向、流量、速度和其他的参数。电磁阀可以配合不同的电路来实现预期的控制，而控制的精度和灵活性都能够保证。电磁阀有很多种，不同的电磁阀在控制系统的不同位置发挥作用，zui常用的是单向阀、安全阀、方向控制阀、速度调节阀等。 1）当parker派克电磁阀需要长时间开启，并且持续的时间多于关闭的时间应选 用常开型；
2）要是开启的时间短或开和关的时间不多时，则选常闭型；
3）但是有些用于安全保护的工况，如炉、窑火焰监测，则不能选常开的，应选可*通电型。
6、根据环境要求选择辅助功能：防爆、止回、手动、防水雾、水淋、潜水。 phs520s-8-110v-d-f
