Round damper, the Swiss special forces and air conditioning (certified), Benxi damper

 PYF-P-1A smoke damper characteristics: 1. Smoke damper usually was normally closed manual dampers, smoke detectors after a fire control center sent a signal input DC24V, solenoid actuator moves, the valve automatically opens, starts out smoke exhaust fan, when the valve When the temperature reaches 280 ℃, fuse action, the valve is closed damper NC, serve to prevent the fire from spreading along the duct purposes. Manual reset the valve action. 2. Control voltage DC24V, micro switch contact capacity AC380V, 3A, solenoid operating current 0.3A. 3. Smoke damper control and related equipment can be interlocked. Description: PYF-P-1A (near control, normally closed) 70 ℃ damper uses: usually installed on the central air conditioning and ventilation system duct, usually always open, when a fire, the gas pipeline temperature reaches 70 degrees / 280 degrees When the valve is automatically closed within a certain period of time to meet the requirements for fire-resistant stability and fire integrity, played the role of smoke fire retardant stainless steel partitions and ceiling air conditioning vent outlet exhaust valves Material: cold rolled sheet or galvanized steel Size: with the design size color products: Paint or character profiles Features: 1. Open the valve according to the fire alarm or manually operated valve open cycle 2. The output signal is also related equipment chain 3. Optional remote electric type... manually open the multi-leaf outlet pressure delivery outlet outlet pressure is usually used to install a new staircase in the front room floor, smoke shaft wall, can also be installed in the pipe side exhaust system or air terminal. The main functions and characteristics, usually normally closed, electric, manual opening. Output on the start signal. Manual reset closed. 280 ℃ temperature sensor operation, the valve is closed again. Using thin body, reduce operating box size, increase the effective area of ??the ventilation exhaust. The main technical parameters: operating voltage / current DC24V / 0.5A. Leakage Rate: 290m3 / m2 · h≤700 (when pressure 1000Pa). Temperature sensor operating temperature of 280 ℃. Leafy exhaust port according to national standards for aisle or smoke before the room of the building, windowless room on the exhaust system 280 ℃ damper, mounted on a wall or roof damper, exhaust port or used as anti- pressurized smoke outlet system, when the fire broke out, through the power DC24V or manually open the valve, according to the function of the exhaust system or smoke before the room air, FPKW, FPYKW type in the flue gas temperature reaches 280 ℃, again The valve is closed, blocking airflow. Function: ⑴ smoke detector alarm signals issued by the control center DC24V power output, the exhaust port opens; ⑵ manually open the exhaust port; ⑶ manual reset; when ⑷FPKW, FPYKW type can reach 280 ℃ in the flue gas temperature, the valve again closed; ⑸FPYKW products for remote control (not exceeding 6m); ⑹ output electrical signal when the exhaust port open, circular fire dampers and fire interlock system or other equipment, the Swiss special forces and air conditioning (certified), Benxi damper Limited by Texas Ruili special air-conditioning equipment. Swiss special forces Texas Air Conditioning Equipment Co., Ltd. (www.dzrltkt.com) is a leader in Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs .
