Quick Start to Shuangxin Air Volume Control Valve

2022-09-21

Air valve, the full name of "air volume control valve"; it is mainly used to adjust the air volume in the ventilation system pipeline. In modern smoke prevention and exhaust systems, air volume control valves are also widely used as important ventilation equipment.

Henan Shuangxin, a ventilation equipment manufacturer, will take you to quickly understand the air volume control valve.

Shuangxin air volume control valve
1. The use range and performance of the air valve
Air volume control valves are usually used in ventilation systems and air conditioning systems in "industrial plants or civil buildings", and are used in fresh air transportation, exhaust emission and air purification projects. They can be used as air volume adjustment or closed. According to the test, the air tightness of Shuangxin air valve is good, and its relative air leakage is not more than 5%.

2. Classification of dampers
The air valve is divided into two types: manual air valve and electric air valve, and their valve section size is made according to the national ventilation standard air duct size. Among them, the manual air valve is divided into two types: "handle type and hand wheel type".

The thermal insulation regulating valve has a 35 mm thick thermal insulation layer on the inner side of the connecting rod, and the thermal insulation material is polystyrene, which is easy to install on site and has a beautiful appearance.

3. The electric air valve mechanism is divided into two types of power sources:
a. The power supply is AC220V;
b. The power supply is DC24V.

4. The air valve can also be equipped with manual adjustment function (the maximum opening angle when electric can be limited by manual adjustment) and thermal insulation type (the thermal insulation material is 35mm polystyrene) according to user needs.
