Products Description
Stainless Steel Worm Gear Trunnion Flanged Ball Valve for Corrosive Service
Zhejiang Chenxiang Valve Co., Ltd. offers our stainless steel flanged ball valve for corrosive environments. Desalination plants, chemical acid/alkali media transport, and offshore platforms require strict material and surface treatment. These applications need stainless steel material. They also need to protect the passive film on the stainless steel surface from damage. Our stainless steel worm gear trunnion flanged ball valve limits body material to F304 or F316L austenitic stainless steel. After machining, we perform pickling and passivation treatment. This process effectively restores and strengthens the corrosion-resistant passive film on the material surface. This product serves desalination, marine engineering, chemical, pharmaceutical, and food industries. It handles acids, alkalis, salt solutions, and various corrosive process media. It also works for compressed air, natural gas, nitrogen, oxygen, hydrogen, and steam. Our models include Q347F, Q347N, Q347PEEK, and Q347Y.
Specialized Pickling Process and Material Verification
Our stainless steel worm gear trunnion flanged ball valve uses only F304 and F316L stainless steel. The primary drive is worm gear. Connections are RF, FM, G, M, or RTJ. The structure is a trunnion ball valve. Our factory has a professional pickling and passivation treatment tank. Every stainless steel valve undergoes the complete pickling and passivation process after machining. Before shipment, we use a handheld spectrometer to re-check the material composition. This ensures that F304 or F316L meets ASTM standard requirements. Our ultrasonic cleaning machine removes iron particle contamination from the machining process. This prevents iron ions from damaging the passive film on the stainless steel surface.
Full Certification and Complete Records
Chenxiang Valve holds CE certification and ISO quality management certification. Each stainless steel worm gear trunnion flanged ball valve comes with a complete material report and traceable test records. We provide a 1-year warranty. Export products use wooden case packaging. Trade terms are EXW and FOB. Choose our stainless steel worm gear trunnion flanged ball valve for long-lasting corrosion resistance in your aggressive media pipelines.
