How appropriate choice of valve? Air flow control valve selection, how to choose the air flow control valve? In principle, the system pressure balance of error is within 10% -15%, you can not set the control valve, but in fact only by transfer duct sizes to adjust pressure is very difficult, so the air flow control valve, to be set up air flow control valve to adjust. ① duct branches should be installed at air flow control valve. In the three-way branch office can be set up three-way valve, or the valve in the branch office is located. ② significant adverse loop can not set the control valve to reduce drag losses. ③ available at the required fire damper valve replacement valve outlet ④ at Grille is appropriate outlet with control valve, can be double the amount of wind Grille demanding control valve plate thickness, by adjusting the outlet angle adjustment air volume. ⑤ fresh air should be installed at the entrance to close the switch valve, valve insulation should be installed in cold area, when automatic control, electric air valve should be used. Electric damper manufacturers, Texas which manufacturers damper cheapest? Material: Carbon steel variety of customized air flow control valve, galvanized plate installed in the ventilation and air conditioning system, the return air duct, usually was turned low air volume control valve price fires when the pipeline flue gas temperature reaches 70 degrees off, and in a certain amount of time to meet leakage of smoke and fire integrity requirements, since the role of smoke fire retardant. Fire dampers, spiral duct, electric air valve, valve actuators, valve actuators prices, valve selection and installation, valve manufacturers, valve legends, outlet valve, manual valve, pressure delivery valve custom all kinds of air flow control valve, Gaoping air flow control valve, air-conditioning equipment provided by Hao Yang Hao Yang Air Conditioning Equipment Co., Texas.
