Self-acting Pressure and Flow Controllers


Self-acting differential pressure and temperature controller with flow limitation 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 one control diaphragm. The controller has no handle since the differential pressure setting is fixed.
