The Modulating BFVAH High-Performance Butterfly Valve Actuator is specially designed for reliable control of butterfly valves used in various HVAC systems and equipment. It is compatible with Fluxera BFV butterfly valves as well as suitable butterfly valves from other brands. Featuring an ISO 5211 compliant flange, the actuator can be connected to butterfly valves easily and securely. Its high-efficiency transmission mechanism provides smooth operation with structural self-locking, while the uniquely designed modulating cam enables more accurate valve control.

The BFVAH is equipped with a 3D dual-color ribbon position indicator, providing clear visual indication of the valve position. For convenient operation during power failures, the actuator can be manually operated using the integrated mechanical handwheel. Its condensation protection system uses heating and dehumidification to help prevent moisture-related electrical failures, ensuring dependable operation in varying HVAC environments. The actuator provides high-accuracy valve position control of up to 1%, supporting precise regulation and consistent system performance.

For enhanced safety and durability, the BFVAH features an independent electrical unit design with a strong protective circuit to help ensure safe operation and extend service life. With a high IP67 protection rating, the actuator offers excellent protection against dust and water ingress, making it suitable for demanding HVAC applications.
