AVP Differential Pressure Controller
Brand: Danfoss
AVP(-F) is a self-acting differential pressure controller primarily for use in district heating systems. The controller closes on rising differential pressure.
The controller has a control valve, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version is without handle).
