Differential pressure controllers
Product types shown: 7
AVP (PN 25)
AVP(-F) 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, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version (available on special request) is without handle).
AVP/ AVP-F (PN 16)
AVP(-F) 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, an actuator with one control diaphragm and handle for differential pressure setting (fixed setting version (available on special request) is without handle).
AVPL
AVPL(-F) 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.
