FRP Ventilation Butterfly Valve - Product Overview

The D341W FRP ventilation butterfly valve is an indispensable accessory in the ventilation, air conditioning and air purification projects of industrial plants and civil buildings. It is generally used in the

ventilation system pipelines to regulate the air volume of branch pipes and can also be used for the mixed regulation of fresh air and return air.

I. FRP Ventilation Butterfly Valve - Features:

It features high mechanical strength, easy installation, acid resistance, corrosion resistance, high temperature resistance (180 degrees), and flexible opening. The products are widely applied in industries such as chemical engineering, power, pharmaceuticals, pesticides, dyes, metallurgy, sewage treatment, and Marine aquaculture

2. Pressure environment of FRP air valve: 0.6-10 (Mpa) Nominal diameter: DN50 - DN2000 (mm) and can be customized according to customer requirements. Advantages of FRP air valves: light and hard, non-conductive, high mechanical strength, corrosion-resistant, easy to install, and high temperature resistance.

3. The FRP butterfly valve designs the main corrosion-prone components such as the valve body and valve plate as FRP materials. The types of fibers, fiber fabrics and resins used in the FRP components are determined by the working conditions of the butterfly valve. The main shape of the FRP valve body is a straight tube. Its structural feature is that it is based on a section of FRP straight tube and then made by adding flanges and sealing rings. This type of butterfly valve features strong corrosion resistance, low cost, and simple and flexible manufacturing process.

4. The connection dimensions of the double-leaf air volume regulating valve are the same as those of the rectangular and circular air ducts specified in the fiberglass reinforced plastic pipe standardization.

5. The blades of the FRP air volume regulating valve are of split type and forward type. It is used as a regulating valve in ventilation FRP pipe fittings, air conditioning and air purification systems.

6. Through experimental determination, it has been found that the FRP air volume regulating valve has good air tightness, with a relative air leakage rate of about 5%, and excellent regulating performance.

7. Made from high-quality vinyl ester resin as raw material, it is manufactured by the "winding + hand lay-up" molding process. The surface is coated with anti-ultraviolet and anti-aging gel coat, featuring anti-corrosion, high-temperature resistance, anti-aging and many other properties. It is an essential pipe fitting for chemical, food processing and sewage deodorization pipelines.

D341W FRP ventilation butterfly valve is widely used in industrial and mining, civil building HVAC system, sewage and waste gas treatment system to accurately adjust the air flow, is one of the key equipment to control the frequency meter, ventilation mode in various environments. Its main characteristics are flexible operation, low noise, small leakage, (closed type leakage < 0.5%) wide working temperature area, reliable structure, safe and convenient.
