Damper is a device used to regulate the flow of air in a ventilation duct. There are many different types of air valves depending on how they are divided into use, or size, and design. If you are looking for this product, follow the article below
Damper Features
The air valve works automatically, without the control from the direct agent. When there is no air flow, the valve will automatically close to limit the risks. The process is done quickly and accurately. This further confirms the extremely important role of this detail.
Damper Functions
The effect of the product is to adjust the air flow. In wind pipelines, they play a very important role. Thanks to the wind valve system, you can adjust the flow of the wind according to the needs of the building or construction work.
The product helps the air conditioning and ventilation system to operate more stably and smoothly. Minimize overload or cause problems during use.
Normally, products are made from stainless steel, galvanized steel. These are good materials, safe and durable. In addition, they are also resistant to rust and abrasion, very suitable for the weather in Vietnam.
Common types of Dampers
There are many types of air valves on the market today. Here are some popular products that are highly appreciated by P69 Mechanical Factory
1. Round Damper
Usage characteristics
– Used to adjust the supply (return) air flow in the ventilation system
– Can be installed in various positions, usually behind the air box or directly on the supply (return) pipe.
Crafting materials and colors
Products are usually made of 2 main materials: stainless steel or galvanized steel
– Can use worm wheel or lever to make hand valve.
The product helps us to adjust the supply and return air volume very easily and conveniently.
2. Non-return Damper
Usage characteristics
– The product is only used on the supplied airline, not on the return airline.
– Specially designed so that when the airflow through the valve will open automatically when the wind moves in the opposite direction, the valve will automatically pile up.
– To increase efficiency, an additional motor can be used.
Crafting materials and colors
– Products can be made of stainless steel or galvanized steel.
3. Louver Damper
Usage characteristics
– Is a type of air valve used to adjust the amount of air on both supplies and return airlines.
– Depending on the purpose of use, the louver valve is installed with the return or supply air outlet at the mouth of the air box or the neck of the louver.
– Air gate valve with door used to regulate the air is made up of many pieces of nau, in which, depending on actual requirements, each part has its own adjustment screw. This is one of the types of wind valves with a special structure, closely following the actual requirements of construction.
Crafting materials and colors
– The louver valve is also made of 2 main materials: Inox (0.6 – 2.0mm thick) and zinc-coated corrugated iron.
4. Square Damper
Usage characteristics
– Square air valves are used in ventilation systems or in air conditioning systems and are installed on the return or supply air lines depending on the usage situation.
– The air flow can be adjusted by the motor or manually adjusted by hand.
Using the square air valve, the return and supply air volume can be adjusted very easily and quickly.
Crafting materials and colors
– Made from 2 common materials such as: galvanized steel or stainless steel.
– Use the lever or the worm wheel to make the square air valve.
5. Electric Damper
Usage characteristics
– Solenoid valves can be used in ventilation systems or in air conditioning systems and are installed on the return or supply air depending on the intended use.
– The airflow is adjusted by the motor, so it has high efficiency.
Using the solenoid valve, the return and supply air volume can be adjusted very easily and quickly
Crafting materials and colors
– Usually made of 2 main materials: stainless steel or galvanized steel.
– The solenoid valve has an opening and closing mechanism according to French standards.
6. Fireproof Damper
Usage characteristics
– Fire extinguishing valve is a type of wind valve commonly used in ventilation systems or air conditioning systems.
– When using the fire extinguishing valve in the ventilation system or the air conditioning system, it is possible to stop the fire in time thanks to the special lead wire.
Crafting materials and colors
– Made of 2 main materials: Inox (0.8 – 2.0mm thick) and zinc coated corrugated iron.
– The fuse in the valve is verified to meet the standards at the Vietnam Quality Measurement Department.
