General Knowledge on “PVC Duct Butterfly Damper Valve”

Air damper means the valve or a plate which can prevent or adjust/regulate air flow volume in the pipe or ventilation duct, chimney pipe, VAV box device, air handling machine, or other air processing equipments. This PVC damper valve is manufactured for suiting for flowing all corrosive and non-corrosive gas environments, high and low temperature service as well.

  • PVC air damper is non-toxic, health, stand high temperature;
  • Anti-rust: PVC air damper can withstand PH value in a wide range of temperatures, high concentrations in the range of 1 to 14 acid and alkali corrosion;
  • Wear-resistant, non-fouling: PVC air damper has uniform and smooth tube inner wall small,small flow resistance and no scaling;
  • Reducing vibration and noise: PVC air damper has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
  •  anti-cracking: PVC material is good elasticity,which makes pipes and fittings sectionally together with the expansion of the liquid frost without bursting.
  •  anti-condensation, less heat loss: PVC material is a poor thermal conductor, reducing condensation and reduce heat loss.
  • Easy Installation: PVC damper valve is light weight, easy to install and operate, meltable and has weldability.
  • Long service life: PVC duct damper valve systems can serve 50 years.

General Knowledge on “Volume Control Damper”

Volume Control Damper,also called air volume control valve,VCD in brief,is a device by adjusting the opening and closing angle of the blades to control air flow volume, mainly installed in rectangular or circular duct ventilation system. Widely used HVAC projects and systems, to adjust air flow accurately.It is one of the key devices to achieve a variety of environments under control ventilation mode. Its main feature is manually adjustable, flexible operation, low noise, leaking a small amount (closed type leakage <0.5%) Operating temperature region wide, reliable structure, safe and convenient.

Volume Control Damper structural features
(1) the air flow control valve in the unity of the whole blade width four sizes, leaf-shaped diamond-shaped double blades, vanes between soft lap, so good airtight performance.
(2) air volume control valve body architecture After 2 mm cold rolled galvanized sheet molding, carbon dioxide gas welding or welding by ordinary Q235 plate processing; blades with 1 mm cold rolled galvanized sheet for corrugated, two synthetic spot-square shaft inserted, or 2 mm G235 steel cold forming, punching chip interpolating axes or welding circular shaft.
(3) The damper is divided into by manual,by electric(motorized type),and according to the materials used,it can be divided : iron, galvanized sheet, aluminum plate, stainless steel (body structure and size specifications are same with different material).

General Knowledge on “Volume Control Damper for round air duct or circular ventilation pipe”

Air damper means the valve or a plate which can prevent or adjust/regulate air flow volume in the pipe or ventilation duct, chimney pipe, VAV box device, air handling machine, or other air processing equipments. This PP damper valve is manufactured for suiting for flowing all corrosive and non-corrosive gas environments, high and low temperature service as well.

  • PP air damper is non-toxic, health, stand high temperature;
  • Anti-rust: PP air damper can withstand PH value in a wide range of temperatures, high concentrations in the range of 1 to 14 acid and alkali corrosion;
  • Wear-resistant, non-fouling: PP air damper has uniform and smooth tube inner wall small,small flow resistance and no scaling;
  • Reducing vibration and noise: PP air damper has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
  •  anti-cracking: PP material is good elasticity,which makes pipes and fittings sectionally together with the expansion of the liquid frost without bursting.
  •  anti-condensation, less heat loss: PP material is a poor thermal conductor, reducing condensation and reduce heat loss.
  • Easy Installation: PP damper valve is light weight, easy to install and operate, meltable and has weldability.
  • Long service life: PP duct damper valve systems can serve 50 years.

Air Ventilation Anti-Vibration Devices

Air Ventilation system equipment should be designed or installed to avoid noise or vibration nuisance to neighbours. Vibration from equipment will interfere with the smooth running of machinery and equipment, shortening their service life. Therefore,a good vibration damper is very important.Good damper not only can reduce vibration and noise from equipment,but also can prolong service years of equipment.It let the system run steadily,and thus reduce time of maintenance and save energy.

General Knowledge on “Fire Damper”

Main Usage
(1) usually was turned on, when a fire in the exhaust pipe when the flue gas temperature reaches 280 degrees off, and to meet the leakage amount of smoke and fire integrity requirements within a certain period of time, from the effects of smoke fire retardant
(2) allows the valve is closed by DC24V power; (electric type smoke damper)
(3) manually shut down or manual reset;
(4) closed DC24V electric reset; (automatic type smoke damper for local inconvenience manually operated)
(4) the output signal of the valve is closed, interlocked with other fire-fighting equipment.

Advantages:
1, the amount of air leakage is low, airtight performance;
2, the electric current consumption small open;
3, strong corrosion resistance and long service life; (made of stainless steel type)
4, flexible actuator drive, feedback, interlock signal accurately.

Types:
1. normally open type Fire Damper;
2. normally closed Fire Damper;
3. Remote control type Fire Damper (rope-controlled);
4. Automatic reset type Fire Damper;

Function:
2.1 Fire Damper function normally open as follows:
2.1.1 usually was normally open state, when the fire broke out, after DC24V power output by the control center, the valve automatically closes.
2.1.2 When the pipe temperature reaches 280 ℃, fuse action, the valve automatically closes.
2.1.3 Output signal the valve is closed, interlocking exhaust fan stops.
2.1.4 manually shut down, manually open.
2.2 normally closed smoke damper, the following functions:
Normally closed smoke damper, also known as secondary smoke damper action.
2.2.1 usually was normally closed when the fire broke out, by the control center DC24V power input, quickly open the valve.
2.2.2 Output valve open signal, interlock control fire exhaust fan.
2.2.3 manually open, manual reset closed.
2.2.4 When the pipe temperature reaches 280 ℃, fuse action, the valve is closed again.
2.3 Remote control type smoke damper (rope-controlled) function as follows:
2.3.1 has a normally closed type smoke damper all the features
2.3.2 can be remotely opened manually, manual reset closed.
2.3.3 Rope control distance standard 6m (long can be customized)
2.4 automatic reset type smoke damper function as follows:

2.4.2 When the pipe temperature reaches 280 ℃, the fuse action, the valve automatically closes.
2.4.3 can be manually opened.
2.4.4 After the valve is opened, without manual reset, simply enter DC24V power, the valve can be automatically reset to its original closed position (this function is limited to the first temperature sensor is not operating, such as temperature and motion sensors need to be replaced after the temperature sensor can still use this feature).
2.4.5 Output valve open signal, interlock control exhaust fan start and stop.
2.4.6 If memory alloy temperature sensors, can be used repeatedly without replacement.

Functions and Features:
