Description
The Belimo CQKBUP-LL Electrical Actuator Valve On/Off 100–240VAC is an electromechanical controller that provides automatic opening and closing regulation for compatible valves based on electrical command signals. It operates in a normally open configuration to ensure predictable valve response during power conditions. In HVAC systems, this actuator regulates water or air flow through control valves, enabling coordinated operation of heating and cooling circuits for stable temperature management and system balance. It is used in building automation applications where reliable switching control and consistent flow regulation are required for efficient system execution.
