PROPORTION AIR压力控制器QB3系列介绍
QB3压力控制阀是一个完整的电子压力调节套件，包括两个进料和排气电磁阀，一个控制电路，一个压力传感器，一个集成的空气先导式体积增压器和一个坚固的外壳。压力传感器直接连接到控制压力，因此闭环电子装置和模拟监控器信号可以显示过程中的实际情况。
不断将模拟监控器信号与命令信号进行比较，以达到所需的设定压力。QB3压力控制阀提供高流量和出色的可重复性。这种紧凑的包装可以以任何方向安装（例外：仅垂直安装且满量程压力低于10 PSI），并且不受工业环境的影响。
The QB3 pressure control valve is a complete electronic pressure regulating package consisting of two feed and bleed solenoid valves, a control circuit, a pressure transducer, an integrated air pilot operated volume booster and a rugged housing. The pressure transducer is connected directly to the control pressure so the closed-loop electronics and analog monitor signal can show you what is really happening in your process.
The analog monitor signal is constantly compared against the command signal to achieve your desired set pressure. The QB3 pressure control valve offers high flow and great repeatability. This compact package can be mounted in any orientation (exception: only vertical with full scale pressures below 10 PSI) and is immune to the rigors of the industrial environment.
