FHF WS-FK fire damper
- Commodity name： FHF WS-FK fire damper
- Product Description
- Technical parameters
-
Performance ：
1、 Normally open. When the airflow temperature in the pipe reaches 70℃ ，the temperature sensor activates, and the valve automatically closes.
2、 The valve can be manually opened and closed, and manually reset after operation.
3、 The valve has six manual adjustment levels for airflow volume.
4、 Can output valve closing signal.
Structure ：
Main components: valve body, blades, shaft, bushing, temperature sensor, actuator, etc.
When φ size ≥φ400, the blade is reinforced in the middle
Maximum manufacturing size of the valve: φ800
Specifications φ≥700, L=320; φ<700, L=210

Precautions
1. Users should not paint the outside of the actuator during use, and should not 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 professionals. Regular checks of opening, closing, electrical signal operation, and temperature sensor should be performed every six months during normal use.
