FHF WSDj-FK-S fire damper
- Commodity name： FHF WSDj-FK-S 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 motor in the actuator is energized, the valve automatically closes, and outputs a closed electrical signal.
2、 The DC motor drives the reset after the valve action.
3、 The valve can be manually closed and manually reset.
4、 When the temperature rises to 70℃ ，the temperature sensor activates, and the valve automatically closes.
5、 Action signals or reset signals are fed back to the control center and the starting interlock device.
6、 The valve has six manual adjustments for airflow.
Structure ：
Main components: valve body, blade, shaft, bushing, temperature sensor, actuator, stainless steel spring plate, torsion spring, etc.
Maximum valve size: 1250×800
Matching actuator model: JFHF WSDj-FYK
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, as this may cause malfunctions.
2. Fire dampers are critical for life safety and must be installed and commissioned by qualified personnel. Regular checks of opening, closing, electrical signal operation, and the temperature sensor should be performed every six months during normal use.
