Bellows Sealed

The valve incorporates a conical disc with a streamlined geometry that effectively eliminates particulate impurities, ensuring a consistent sealing performance and extended operational lifespan; a dual-sealing mechanism combining a metal bellows and packing to provide redundancy in leak prevention; a patented stem-centering design that minimizes vibration and acoustic noise, thereby enhancing the stability and longevity of the bellows; and an advanced coated sand casting process utilizing binders and additives to produce high-integrity castings with reduced porosity and cracking, resulting in superior mechanical strength and durability."
