The Danfoss ASV-I DN 15 partner valve with female thread is a multifunctional control valve designed for installation in the flow pipe of a heating system. The valve combines the functions of flow presetting, shut-off valve and flow measurement in a single compact body.

The ASV-I valve serves as a partner valve for the ASV-P or ASV-PV differential pressure controller. It allows the required flow rate to be preset in the controlled branch of the heating system by simple adjustment. The measuring nipples are integrated directly into the valve body and are used for flow measurement in the flow pipe. The valve body also features a connection port for the impulse tube, ensuring connection to the ASV-PV valve.

When the ASV-PV valve is used together with the ASV-I, automatic differential pressure control can be utilised in combination with maximum flow limitation for individual branches of the heating circuit.

Warning: If the ASV-I valve is not used together with the ASV-P or ASV-PV, a Danfoss plug, code 03L8174, must be used to seal the impulse port.
