AVPQT



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

The controller can be combined with AVT or STM thermostats.

The controller has a control valve with adjustable flow restrictor, connection neck for thermostat, an actuator with two control diaphragms and handle for differential pressure setting.
