Mr Bob MccabeWe have purchased 6 sets Roller Shutter Door for our candy factory from your company. Good quality! Good sevice! We will purchased other clean room equipment from your company later.
Mr ManhThis year we are going to build a mobile phone screen electronics clean factory.We send Hongkong YaNing a list of products we need,Unexpectedly, they soon gave me a very detailed quotation and drawings, and gave us a lot of good advice. Very professional, good service, good product quality! We decided to place an order.

Aluminum air volume control valve air diffuser damper for ventilation system
1. Air volume control valve description
The air volume control valve is an indispensable central air conditioning terminal fitting in the ventilation, air conditioning and air purification engineering of civil buildings of industrial plants. It is generally used in the air conditioning and ventilation system pipelines to adjust the air volume of the branch pipes, and can also be used for fresh air and return. Mixed regulation of the wind.

|11||Action method||At 280 degrees, temperature-fuse protector motion, the valve under the spring pulled shut automatically, 0-90 degrees manually adjust the blade opening angle.|
|12||Reset method||Manual reset|
|13||Air leakage||In standard conditions, as the differential pressure is 300 Pa, the air leakage is less than the national standards.|
2. Air flow control valve features:
(l) The size of the split-split air volume control valve is the same as the size of the rectangular air duct standardized by the national ventilation pipeline.
(2) The air flow control valve vane is a split type and a forward open type, and is used as a regulating valve in ventilation, air conditioning, and air purification systems.
(3) The air-tightness of the air volume control valve is good through tests, and the relative air leakage is about 5%, and the adjustment performance is good.
3.Air volume control valve structure:
(l) The air volume control valve is unified in four sizes for the blade width, the blade shape is a diamond-shaped double blade, and soft laps are used between the blades, so the hermeticity is good.
(2) Air flow control valve body frame is cold-rolled with 2 mm galvanized sheet and then welded with carbon dioxide gas or welded by ordinary Q235 plate; the blade is cold-rolled with 1 mm galvanized sheet into corrugated shape, two pieces Synthetic spot welding insert square shaft, or 2 mm G235 steel plate cold forming, single piece punching insert square shaft or welding round shaft.
(3) The regulating valve is divided into manual and electric, and it is divided into four types according to the used materials: iron plate, galvanized plate, aluminum alloy plate and stainless steel plate. The valve body structure and size are the same.
4.Air volume control valve application:
Widely used in industrial and mining, civil buildings, HVAC systems, and the precise adjustment of air flow is one of the key equipments for controlling ventilation modes in various environments. Its main features are flexible operation, low noise, small leakage, (closed leakage <0.5%), wide working temperature range, reliable structure, and safety and convenience.
