The forged steel bellows seal globe valve addresses the persistent issue of stem gland packing leakage, which leads to significant energy losses and increased factory downtime. Beyond the financial impact, gland leakages pose serious environmental, ecological, and health risks to workers. The leakage of sensitive materials can result in fire hazards, explosions, and damage to equipment due to corrosive substances. Additionally, if leaked air infiltrates the pipeline, it can create flammable, explosive, or poisonous mixtures. Traditional gland packed valves often require constant maintenance, complicating accessibility and further exacerbating operational challenges.

Major Advantages

Bellows Seal Element: The key component of bellows sealed globe valves is the metal bellows. This part connects the cover and stem through automatic roll welding, ensuring that the stem remains leak-free.
Enhanced Seal and Longevity: Thanks to the conical and streamlined design, the disc provides a reliable seal and boasts a longer service life.
Double Seal Design (Bellows + Packing): The combination of bellows and packing offers superior protection against leakage, ensuring an excellent seal.
Grease Nipple: This feature allows for direct lubrication of the stem, nut, and sleeve, enhancing the valve's performance and durability.
Ergonomic Hand Wheel: Designed for ease of use, the ergonomic hand wheel ensures longer service life and more straightforward operation.
