ZPQ-01/ZPQ-02型气动阀门定位器概述

是以220V交流单相电源作为驱动电源，接受来自计算机调节器或操作器的4-20mADC，或者1-5VDC输入信号来运转的全电子式执行机构，机内有伺服系统，无需另配伺服放大器，关键部件“控制器”采用*的混合集成电路，并用树脂浇铸固化，经老化处理，可靠性高，防潮，防震。用电位器调整零点、行程、灵敏度，方便易行；用功能开关任意选择正、反动作、选择断信号的三种状态。同时，执行器具有过载保护、温度保护及压缩弹簧保证阀门的关严等三种保护功能。是一种具有高可靠性的产品，可与各种直行程调节阀门组成电动调节阀。

 

 

ZPQ-01/ZPQ-02型气动阀门定位器可与气动调节阀，直行程气动活塞调节阀及角行程气动调节阀配套使用的辅助仪表，它接受气动调节仪表给出的20~100kPa信号来控制调节阀的行程，又经由反馈系统的作用，确保阀芯位置按调节仪表来的气动信号，正确执行，从而实现阀芯的准确定位。
