The VFH hot air butterfly valve is designed with a single eccentric disc and utilizes spring force to reduce clearance, enabling more precise regulation and preventing disc flotation;

·

Driven by handle, servo motor, and electromagnetic actuator;

·

To enhance mechanical strength, sealing performance, and corrosion resistance of components, all parts undergo special impregnation and surface treatment, making them sufficiently resistant to mechanical, chemical, and high-temperature effects in harsh environments.

Product Application

The VF/VFH series butterfly valves can use auxiliary power such as electric or electromagnetic, or manual operation to achieve regulation.

Continuous proportional control. For combustion air, the M..Z electric actuator + VF butterfly valve enables continuous adjustment, while a manually operated VF..L butterfly valve is installed downstream to limit the maximum flow. (The manual butterfly valve features scale indication and a locking function.)
