Molybdenum-bearing austenitic stainless steel industrial valve
316 Katup Kupu-Kupu Tiga Offset Baja Tahan Karat
A widely specified corrosion-resistant valve material for chemical, farmasi, water and general process systems. The triple offset butterfly valve configuration is engineered for compact high-temperature or severe-service process isolation.
Apa itu a 316 Katup Kupu-Kupu Tiga Offset Baja Tahan Karat?
A 316 Stainless Steel Triple Offset Butterfly 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 quarter-turn metal-seated design using three geometric offsets to reduce seat rubbing and support severe-service isolation.
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. Seat-stack design, pressure direction, leakage class, shaft loading, thermal cycling and actuator torque are configuration-specific.

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.
What are the three offsets?
They separate the shaft from the seat and body centerlines and add a conical sealing geometry, allowing rapid seat disengagement during opening.
Is every triple offset butterfly valve bidirectional?
TIDAK. Some designs have a preferred pressure direction or different leakage capability by direction. Confirm the tested performance of the exact configuration.
Bisa 316 Stainless Steel be used for every component in this triple offset butterfly 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.
