The Belimo H779R three-way lift valve is designed for closed circuits of cold or hot water and continuous water-side regulation in air conditioning and heating systems. It is therefore suitable for air conditioning, heating, and ventilation applications. To operate the valve, a lift actuator from the Belimo brand (NV, SV, EV, LV series) is required, which moves the valve stem to the desired position.

The valve installation can be performed vertically or horizontally, but under no circumstances should the valve stem point downwards. It is also important to maintain the direction of the medium flow through the valve, according to the arrow stamped on the valve body. The valves are maintenance-free.
