Product introduction
Product Description:
Smoke Exhaust & Fire Proof Damper (Normally Close)（PFHX-280B）
Usually it is closed. When the fire occurs, the valve is opened quickly to exhaust smoke by the output of DC24V power. It automatically shut down when the temperature of gas in the pipeline reaches at 280 degree. The output signal of opening valve can interlock with other equipments.
Application:
Applied to the pipeline of smoke exhaust system.
Features:
(1) Using galvanized steel as material to make sure good insulation performance, fire & corrosion resistance.
(2) Duration, long service life.
(3) Easy installation.
(4) The flange is bended directly by the frame.
(5) The valve size and color can be customized according to customer's requirements.
(6) Output open valve signals, can connect with other equipment
Advantages:
(1) Excellent quality control processes, all products have been inspected strictly.
(2) The quality of products has reached the standard of “Code of acceptance for construction quality of ventilation and air conditioning works" (GB50243-2002) and "Fire dampers for building venting and smoke-venting system" (GB15930 2007).
(3) Complete accessories production and distribution make it easier to install.
