280 ℃ damper | Anshan damper | Swiss special forces air conditioning

 PYF-P-1A smoke damper characteristics: 1. Smoke damper usually was normally closed when the fire after a smoke detector signal sent by the control center input DC24V, solenoid actuator moves, the valve automatically opens, starts out smoke exhaust fan, the valve when the temperature reaches 280 When ℃, fuse action, the valve closes, serve to prevent the fire from spreading along with the duct. Manual reset the valve action. 2. Normally closed damper control voltage DC24V, micro switch contact capacity AC380V manual dampers, 3A, solenoid operating current 0.3A. 3. Smoke damper control and related equipment can be interlocked. Description: PYF-P-1A (near control, normally closed) circular damper: Install in the ventilation, air conditioning system, the return air duct on the road, usually was turned on when the gas pipeline fire when the temperature reached 70 ℃, fusible sheet fuse, the valve automatically closes in the torsion force, within a certain period of time to meet the fire resistance stability and fire integrity requirements damper, smoke fire retardant effect from the valve. When the valve is closed, the output signal is turned off. Beautiful appearance, rust-proof, easy to install, high-performance, low price FSD (G), FSD (F) Simple fire damper valve structure of the main components: body, valve leaves, shafts, bushings, valve actuators rectangle Thickness: L = 210,260 flange width of three to 30, 40 to 30 conventional explosion damper, when designing or ordering please specify the size W> 1250, the increase in the middle frame, blade separation. Body area ≥1m2, actuators mounted two. FSD (G), FSD (F) Simple fire damper valve main fuse holders intraoperative parameters Operating temperature: 70 ℃ (or 280 ℃) Valve fire rating: 1.5h air leakage; ≤700m3 / m2 .h 280 ℃ fire Valve | Anshan damper | Swiss special forces air conditioning provided by the Texas Air Conditioning Equipment Co.
