AVPL Differential Pressure Controller
Brand: DanfossAVPL 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 and an actuator with one control diaphragm.
It can be used on primary side of house substations for smaller systems such as one and two-family houses.
The controller could be used to control the differential pressure across radiator systems and similar systems to keep a constant differential pressure even with a variable system resistance kva and/or supply pressure Δp₀.
