AFP VFG2 (VFG 21) is a self-acting differential
\npressure controller primarily for use in district
\nheating systems. The controller closes on rising
\ndifferential pressure.
\nThe controller has a control valve (flange
\nconnection), an actuator with control diaphragm
\nand a spring for setting differential pressure.
