PFHF WSDc-K smoke exhaust fire damper
- Commodity name： PFHF WSDc-K smoke exhaust fire damper
- Product Description
- Technical parameters
-
Performance ：
1、 Normally open, in case of fire, the smoke (temperature) sensor sends an electrical signal ( DC24V) to the control center, the electromagnet in the actuator is energized, the valve automatically closes, and outputs a closed electrical signal.
2、 The valve can be manually closed or 280℃ closed by the temperature sensor.
3、 Manual reset after valve operation.
Structure ：
Main components: valve body, blade, shaft, bushing, temperature sensor, actuator, stainless steel spring plate, torsion spring, etc.
W direction plus intermediate frame, blade separation
Maximum valve size: 1250*800
W×H matches the duct size, and the flange size is the same as the flange of the metal rectangular duct in national standard GB50234-2002.

Precautions
1. Users should not paint the outside of the actuator or add oil to the electrical components during use, as this may cause malfunctions.
2. Fire dampers are critical for life safety and must be installed and commissioned by professionals. Regular checks of opening, closing, electrical signal operation, and temperature sensor should be performed every six months during normal use.
