Fine Chemical Process Pipelines

For the fine control requirements of corrosive media (such as chlorine and concentrated sulfuric acid), the bellows stop valve uses CF3M austenitic stainless steel valve stems and PFA bellows sealing components to achieve 100,000 cycles without leakage. The V-type valve disc design with a micro-adjustment handwheel can achieve nano-level flow control between 0.5-15mm openings, and the material uniformity verified by a chemical element analyzer ensures 30 years of maintenance-free operation in a chloride environment.
