Molybdenum-bearing austenitic stainless steel industrial valve
316 Katup Bola Apung Stainless Steel
A widely specified corrosion-resistant valve material for chemical, farmasi, water and general process systems. The floating ball valve configuration is engineered for fast on-off isolation in process and utility piping.
Apa itu a 316 Katup Bola Apung Stainless Steel?
A 316 Stainless Steel Floating Ball Valve combines a molybdenum-bearing chromium-nickel austenitic stainless steel family with improved resistance to localized corrosion compared with 304 in many environments with a compact quarter-turn isolation design in which line pressure loads the floating ball against the downstream seat.
316 is a common market description; cast valve bodies are generally specified as CF8M or low-carbon CF3M, while forged parts use F316 or F316L. Floating-ball suitability depends on size, tekanan diferensial, seat load, operating torque and cavity-pressure behavior.

Pertanyaan yang sering diajukan
What is the cast equivalent commonly used for 316 valve bodies?
ASTM A351 CF8M is commonly associated with cast 316-type chemistry and CF3M with low-carbon 316L-type chemistry. They remain distinct casting grades with their own requirements.
Adalah 316 stainless steel suitable for seawater?
Tidak secara otomatis. Suhu, oksigen, kecepatan, celah-celah, deposits and residual chlorine can cause localized attack. Rangkap, super duplex or higher-alloy materials are often evaluated for demanding seawater duty.
Why is PMI requested for 316 katup?
PMI helps distinguish molybdenum-bearing 316-type components from visually similar 304-type material and supports material traceability in alloy-controlled projects.
How does a floating ball valve achieve shutoff?
Line pressure moves the ball slightly toward the downstream seat, producing pressure-assisted sealing. Seat material and geometry control leakage and operating torque.
When should a trunnion-mounted design be considered?
Trunnion mounting is commonly evaluated as size, tekanan, torque, seat-load control or pipeline-service requirements increase.
Bisa 316 Stainless Steel be used for every component in this floating ball valve?
Tidak secara otomatis. Batas tekanan, memangkas, batang atau poros, tempat duduk, sedang mengemas, bahan paking dan baut memiliki tugas mekanis dan korosi yang berbeda. Bill of material yang lengkap harus direkayasa untuk layanan tersebut.
