Factory For 3 Swing Check Valve - Expansion joint bellows (adjusting long) – Like Valve Detail:

Feature

1. Compensating thermal expansion: It can compensate for many directions, which is much better than the metal compensator which can only be compensated by single mode.

2. Compensation for installation error: Because the system error is unavoidable in the process of pipeline connection, the fiber compensator can better compensate the installation error.

3. Noise and vibration attenuation: Fiber fabrics and insulation cotton have the functions of sound absorption and vibration isolation, which can effectively reduce the noise and vibration of boilers, fans and other systems.

4. No back thrust: Because the main material is fiber fabric, the transfer is weak. The use of fiber compensator can simplify the design, avoid using large supports, and save a lot of material and labor.

5. Good resistance to high temperature and corrosion: Fluoro plastics and silicone materials have good resistance to high temperature and corrosion.

6. Good sealing performance: There is a relatively perfect production and assembly system, and the fiber compensator can ensure no leakage.

7. Light weight, simple structure, easy installation and maintenance.

8. The price is lower than that of metal compensator and the quality is better than that of imported products.
