Smoke damper and damper differences? Class 1 fire, fire dampers: the role of fire air volume control valve which manufacturers cheap, 700C temperature fuse automatically shut down, air flow control valve linkage damper phone manufacturers, ventilation and air conditioning systems used within the duct 2, smoke dampers: to rely on tobacco What a sense of control action is good air flow regulator valve quality, power off (smoke), can also be turned off automatically 700C temperature fuse (fire) is used in the ventilation and air conditioning duct systems. Fire dampers, spiral duct, electric air valve, valve actuators, valve actuators price, selection and installation of valve, valve manufacturers, valve legends, outlet valve, manual valve, pressure delivery valve plate The new form of zinc ventilation pipe flange total air volume control valve butterfly valve system using this type dish board short midline structural steel welding and structural design and manufacture of air-flow valve, compact, light weight, easy to install, small flow resistance, flux large, to avoid the impact of high temperature expansion, easy operation. Body without connecting rods, bolts, etc., reliable, long service life. You can multi-site installation, the flow of influence from the media.
