A BMS valve is a type of valve used in the building management system (BMS) to control the flow of air and other fluids. It is typically used in commercial and industrial buildings to regulate the temperature, humidity, and air quality of the building. The valve is connected to the BMS and can be used to open and close the flow of air or other fluids, as well as adjust the pressure of the system. The valve is also used to control the flow of water, steam, and other liquids. The BMS valve is designed to be reliable and durable, and is often used in conjunction with other components of the BMS, such as sensors, controllers, and actuators. The valve is also used to regulate the temperature of the building, as well as to monitor and control the air quality. The BMS valve is an important component of the building management system, and is essential for maintaining a comfortable and safe environment for occupants.
