BURKERT通用调节器204639具有紧凑型的结构方式，非常适合同样采用紧凑型设计的调节系统。这种调节器经测试可兼容与所有 Bürkert 比例阀和传感器，在使用标准信号（4-20 mA、0-10 V 或 PWM 输出信号）的前提下，可以与各种非 Bürkert 调节阀相组合。这种具有 PI 特性的过程调节阀，配备了大量的附加功能。通过 3 个模拟输入端，可以将工艺实际值作为标准信号 (4-20mA / 0-10V)、电阻信号 (PT100) 或频率信号读入。通过电流或电压标准信号或者键盘，可以规定工艺额定值。特别适合温度调节任务，可以设计其下方安装有流量调节装置的级联式结构。通过控制比例阀和过程阀，可以在流体技术领域中完成各种各样的调节任务，也可将其应用于液态的或气态的介质。
