The Danfoss ASV-I DN 20 valve is a multi-purpose partner valve designed for balancing heating and cooling systems. It integrates the function of flow presetting, shut-off valve and flow measurement in one compact body. The valve is installed in the supply line of the controlled branch of the heating system.

The valve includes measuring nipples fitted directly on the body and a connection port for an impulse tube, which is used to connect it to the ASV-PV or ASV-P differential pressure controller. When used in the ASV-I + ASV-PV pair, differential pressure control with maximum flow limitation for individual branches of the heating circuit is ensured.

Warning: If the ASV-I valve is not used together with the ASV-P/PV, the impulse port must be sealed with the Danfoss 03L8174 plug.

Functions

• Presetting the required flow rate in the branch of the heating system
• Shutting off the controlled branch (shut-off valve function)
• Flow measurement using integrated measuring nipples
• Connection to a differential pressure controller via the impulse port
• Automatic hydraulic balancing when combined with ASV-PV
