AVPB, AVPB-F (PN 16)

AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.

The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).

AVPB, AVPB-F (PN 25)

AVPB (-F) is a self-acting differential pressure controller with flow limitation primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.

​​​​​​​The controller has a control valve with adjustable flow restrictor, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).

AVPQ (PN16)

AVPQ is a self-acting differential pressure and flow controller primarily for use in district heating systems. The controller closes on rising differential pressure or when set max. flow is exceeded.

The controller has a control valve with adjustable flow restrictor, an actuator with two control diaphragms and handle for differential pressure setting (fixed setting version (available on special request) is without handle).

智能电动驱动器 AMEi 6 iNET

AMEi 6 iNET 驱动器可智能平衡管网，远程调节 区域供暖/制冷系统所用的 AFA 2, AFD 2, AFP 2, AFPA 2, AFPB 2, AFPQ 2 和 AFPQ 2 控 制器的压差 (Δp) 设定值。

​​​​​​​改变热耗就需要改变热量输送。因此，应当 优化每条支管的 Δp。借助 iNET，可远程调节 Δp。水泵优化输入。

智能电动驱动器AMEi 6 iSET

AMEi 6 iSET 驱动器用于智能优化区域供热/制冷系统运行。自动调整暖通空调系统所用 AFP 2、AFPB 2、AFPQ 2 和 AFQMP 2 控制器的压差设定值。

该解决方案适用于最小-最大流量范围宽广的动态区域能源系统（生活热水供应）和尺寸控制不当的设备（控制阀尺寸过大、阀门选型/特征有误、控制精度不佳……）。
​​​​​​​
在部分/低负荷操作条件下，自动稳定功能可通过调整电动控制阀 (MCV) 的压差，监控控制信号和稳定系统工况避免振荡。
​​​​​​​
持续的实时 MCV 操作优化可实现更稳定地控制而无振荡，并输送符合实际需要的流量（防止过流）。
​​​​​​​
​​​​​​​从而稳定二次侧的温度条件、改善一次侧的温差，延长所装设备的使用寿命。
