L=250
STRUCTURE
Main components: Valve body, decorative air outlet, valve blade, shaft, shaftbushing, actuator
Rectangular valve body thickness: L=250mm
Valve flangesare all manufactured as common plate flanges with a width of 30-40mm

PERFORMANCE
It remains normally open under normal conditions. When the air temperaturein the pipeline reaches 70°C, the fuse operates and the valve closes automat-ically. The valve can be manually opened or closed, and manually reset afteractuation. It is equipped with a 6-speed air volume adjustment switch andcan output a valve closing signal.
