Scope of use

Air volume control valves are widely used in industrial, mining, and civil building HVAC systems, industrial waste gas purification systems, and are one of the key equipment to control ventilation modes in various environments.

Material and category

The common materials of the air volume control valve are PP material, stainless steel material, PP material, and galvanized steel plate. The most used in the industrial waste gas purification industry is the PP damper.

Common types of damper:

1. Split multi-leaf control valve

2.Butterfly valve (single leaf regulating valve)

3. Manual air valve

4. Electric air volume control valve

10. Airtight damper

Structural characteristics of the air valve

(1) The air volume control valve has four specifications when the blade width is all the same. The blade shape is a diamond-shaped double blade, and the blades are soft overlapped, so the sealing performance is excellent.

(2) The valve body frame of the air volume dispatching valve is formed by cold rolling of 2mm galvanized sheet and then welded by maintenance welding of carbon dioxide gas or processed and welded from general Q235 sheet; the blade is cold-rolled with 1mm galvanized sheet into a corrugated shape, two pieces It is composed of spot welding inserting square shaft, or 2mm G235 steel plate cold forming, single-piece punching inserting square shaft or welding round shaft.

(7) The dispatching valve is divided into manual and electric. According to the materials used, it is divided into four types: carbon steel plate, galvanized plate, aluminum alloy plate, and stainless steel plate. The valve body structure and specifications are the same.

Classification of PP duct valves

1. One-time regulating valve: If the system is not balanced, it is a regulating valve designed to achieve the required air volume. It is divided into flapper valve, butterfly valve, multi-leaf regulating valve, and three-way valve.

2. Frequently switched regulating valves: Mainly include fresh air valve, primary and secondary air return valve, exhaust valve (including exhaust valve for comprehensive exhaust and partial exhaust).

4. Automatic control valve: Mainly used for automatic adjustment of fresh air, primary return air, and secondary return air. In addition to meeting the requirements of frequently-on-off regulating valves, it should also have good regulating characteristics.
