Pressure Reduction Controllers

AFD 2/ VFG22(1)

The controller is a self-acting pressure reduction controller primarily for use in district heating systems. Direct operated, reliable and high precise controller closes on rising pressure. The controller has a control valve, an actuator with one control diaphragm and spring for pressure setting.

AFD/VFG 2(1), VFGS 2

The controller is a self-acting pressure reduction controller primarily for use in district heating systems. The controller is normally open and closes on rising pressure. The controller has a control valve, an actuator with one control diaphragm and a spring for pressure setting.

AVD / AVDS

AVD(S) is a self-acting pressure reduction controller primarily for use in district heating systems. The controller is normally opened and closes on rising pressure. The controller has a control valve, an actuator with one control diaphragm and a spring(s) for pressure setting.

VFG 2 / VFGS 2

The controllers STFW/VFG(S) 2 and STFW/AFT/VFG 2 are used for temperature control and temperature monitoring of drinking water and heating systems.
