Reliable sealing and outstanding performance are achieved through:
1. Our company employs a secondary sandblasting process, significantly enhancing surface smoothness and improving corrosion resistance.
2. When the valve is closed, the conical sealing surface with a “scraping effect” automatically removes surface impurities, ensuring reliable sealing and a longer service life.
3. The combination of bellows and packing in a dual-seal design (static and dynamic sealing) fully meets the sealing performance requirements of the valve during use, extends service life, and addresses the issue of packing wear in traditional packing globe valves, which can lead to valve seal leakage. This design complies with international and domestic sealing standards.
4. All bellows undergo 100% hydrogen testing, and all valves undergo 100% testing using intelligent testing equipment in accordance with standards, ensuring zero leakage.
4. All bellows undergo 100% hydrogen testing, and all valves undergo 100% testing using intelligent detection equipment in accordance with standards, ensuring zero leakage.
5. Various valve disc designs can be provided based on operating conditions and medium requirements, such as throttling-type valve discs, flat soft-seal valve discs, and globe check-type valve discs.
Why Reliable sealing and excellent function:
1. BAFAW adopts secondary sand rolling and shot blasting treatment, which greatly improves the surface finish and enhances the corrosion resistance.
2. When the valve is closed, the tapered sealing surface with "scraping effect" can automatically remove surface impurities, which can ensure reliable sealing and longer service life of the valve disc.
3. The sealing design of the bellows with packing, static seal and dynamic seal, fully realizes the sealing performance requirements of the valve during use, enhances the mission of use, makes up and solves the problem of the easy wear of the traditional packing stop valve, which leads to the leakage of the valve seal. The problem, in line with international and domestic sealing standards.
4. 100% of all bellows have passed the ammonia test, and 100% of all valves have passed the intelligent testing equipment in accordance with the standard test to ensure zero product leakage.
5. According to the working conditions and medium requirements, various disc designs can be provided, such as throttle type disc, plane soft seal disc, stop check disc, etc.
