One-piece molding valve body PP flame retardant high precision one-piece control variable air volume butterfly valve

1 . Descriptions:

BD-A-DNxxx variable air volume butterfly valve is a pressure-independent butterfly valve specially designed for high-precision, high-response speed (< 1s) intelligent adjustment of required air volume for supply and exhaust air. It is made of PP material and is corrosion-resistant. It has a built-in air volume measurement section based on the Venturi principle for accurate measurement of exhaust air volume. Only 1*D straight pipe section is required for accurate measurement. It comes with a high-precision flow sensor for real-time measurement.

3. About PP variable air volume butterfly valve

1. PP flame retardant material is standard V2 (customizable V0), with good anti-corrosion performance (with third-party test reports for anti-corrosion and flame retardancy);

2. Adopting the Venturi effect nozzle wind measurement structure, the air volume is accurate, the error is less than +/-4%, and the air volume adjustment ratio is 16:1 (with third-party test report);

3. Adopting PP+GF+silicone coated air valve blades, the sealing performance is good and meets the high-density standard (with third-party test report);

4. High-precision flow sensor, real-time measurement;

5. The valve body has flange and socket connection interfaces for easy installation;

6. Fast response speed, response speed <1 second

4. Product Configuration

Integrated control variable air volume butterfly valve

The controller and actuator are designed in one piece, with a simple structure;

2S fast actuator, fast response speed (response within 1S, stable within 2~3S)

5. Application Scenarios

It is mainly used in laboratories with corrosive gas emissions and where precise air volume is required (not suitable for high temperature environments), such as fume hood exhaust, laboratory exhaust and air supply, and animal room exhaust and air supply.
