NORGREN气缸型号

    NORGREN气缸型号市场需求量没达到足以引以他们的兴趣。实际上我们的油库采用国内生产的大流量的双联组合阀，效果会好得多。双联组合阀还常用来控制温度、压力、液位等参数。大阀保证基础量，小阀提供补偿量。在参数相对稳定的系统中，这种位式控制能达相当高精度。好些参数变化较大的系统，变化的速率仍受一定制约，例如温度控制系统，仍受热惯性的影响。所以运用得当的双联组合阀在满足控制要求的前提下相对于调节阀能大幅降低成本。

     NORGREN气缸型号平时不通电，处于微启状态，阀门提供初始流量；给一种电信号，电磁阀全开，提供大流量；给另种电信号，阀门关阀。阀门还带有手动装置， 使得长期关阀时也不需耗电。三位电磁阀可视为一种结构更为紧凑的双联电磁阀，它很方便地实现三位调节，得到了很多应用。进一步的思路是n个大小成一定比例的电磁阀组成2n种流量,类似于数字电路称这种组合阀为数字阀。
