Product Description
Why bellow seal globe valves are more tightly sealed than normal globe valve?
1. Unparalleled Seal Integrity: Unlike conventional globe valves that rely solely on padding seals, Bellow Seal Valve boasts double seals with both bellows and padding. This dual-seal system guarantees an airtight, leak-free performance, ensuring that your operations run seamlessly.
2. Extended Service Life: Equipped with a disc featuring a scraping effect, this cast steel bellows globe valve goes the extra mile in terms of durability. The scraping effect minimizes wear and tear, resulting in a prolonged service life, reducing maintenance hassles, and enhancing cost-efficiency.
3. Corrosion Resistance: The interior seals and bellows of our precision valve are meticulously crafted from stainless steel 321. This high-quality material not only enhances corrosion resistance but also significantly extends the valve's overall service life. You can rely on it for years to come, even in demanding, corrosive environments.
4. Lightweight and Efficient: In addition to its robust features, bellow sealed valve is remarkably lightweight, making it a breeze to operate. Whether you need to open or close the valve, its ergonomic design ensures that the job is done with minimal effort and maximum efficiency.
Cast steel bellows seal globe valve from AFBV is a testament to precision engineering and innovative design. It outperforms conventional globe valves in every aspect, from sealing integrity and service life to corrosion resistance and ease of use.
