FRP Air Valve

FRP Air Valve


FRP wind valve is widely used in industrial and mining, civil construction HVAC systems, precise adjustment of air flow, is one of the key equipment to achieve control ventilation mode in various environments. Its main features are flexible operation, low noise, and small leakage. (Closed leakage < 0.5%) Wide operating temperature range, reliable structure, safe and convenient.


1. Cold resistance: under freezing medium, the pipeline will not be cracked;

2. Corrosion resistance: can choose different corrosion-resistant pipelines according to media requirements;

3. Withstand voltage: According to the pressure requirement of the process, the pressure test is carried out at 1.5 times the pressure required by the process;

4. Heat resistance: temperature range is -50 ~ 150 ° C;

5. Scope of application: chemical medium conveying pipe, various process pipes, pressure water pipes of small hydropower stations on the ground, circulating water pipes of power          plants, sewage collection and extra large seawater, oil and other conveying pipes.

6. The strength of the FRP valve is close to carbon steel, and the rigidity is good.

7. The sealing material is made of PTFE, which has long service life and high temperature corrosion resistance.

8. The valve shaft does not rotate with bearings to avoid switch failure caused by bearing corrosion. The large diameter anti-corrosion shaft is used, which has good rigidity and avoids flexible deformation.

9. All the parts connected with the shaft are machined to ensure accuracy and the sliding connection is more reliable.

10. The thickness of the valve plate is gradient type, the thickest part is up to 45 mm, and the double-sided ribs are reinforced and not easy to be deformed.

11. Plastic, such as PP material valve rigidity is poor, outdoor aging cracking deformation. Alloys such as alloys have good rigidity but are not resistant to dilute acid corrosion. FRP valves have the advantages of plastic and metal alloy materials, good rigidity, aging resistance and corrosion resistance. Compared with metal alloy or lining F4 valves, the price is more affordable.
