HVAC stands for heating, ventilation and cooling. Generally, HVAC systems are used indoors or outdoors to heat and cool residential and commercial buildings.

The medium in the HVAC industry is generally cold air, hot air, water, refrigerant, or hot water. The HVAC industry circulates, cuts off and regulates the medium through pipes and valves.

Since HVAC pipes are generally larger, butterfly valves are recommended. Secondly, because the medium needs to circulate for a long time, and the installation location is not easy to assemble the air source parts, we will recommend the use of motorized valves or manual valve.

As an actuator and valve manufacturer, COVNA offers all kinds of actuator valves and valves for your HVAC applications. What’s more, we could help to custom the valve for your HVAC project.
