Molybdenum-bearing austenitic stainless steel industrial valve
316 Katup Gerbang Baji Stainless Steel
A widely specified corrosion-resistant valve material for chemical, farmasi, water and general process systems. The wedge gate valve configuration is engineered for fully open or fully closed isolation with low open-position pressure loss.
Apa itu a 316 Katup Gerbang Baji Stainless Steel?
A 316 Stainless Steel Wedge Gate 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 full-opening linear isolation design that raises a wedge out of a substantially straight flow path.
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. A wedge gate valve is not normally used for throttling because partial opening can produce vibration and seat or guide damage.

Wedge Gate Valve design and standards
API 600
Common design basis for bolted-bonnet steel gate valves, including material, memangkas, testing and marking requirements.
ASME B16.34
General pressure-temperature and valve design requirements within scope.
API 598
Kerang, pengujian tekanan kursi belakang dan penutupan bila ditentukan.
API 624 / ISO 15848-1
Fugitive-emission qualification is specific to the packing system and qualified valve design.
Wedge flexibility, seat hardfacing, stem/packing system, body cavity drainage, thermal binding risk and operating thrust require service-specific review.
Aman dari kebakaran, emisi buronan, layanan asam, oksigen, kriogenik, Persyaratan klorin dan PED hanya berlaku jika ditentukan secara eksplisit dan didukung untuk konfigurasi yang ditawarkan secara tepat.

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.
Can a wedge gate valve be used for throttling?
Normally no. It is intended for fully open or fully closed service; extended partial opening can damage the wedge, seats and guides.
What is the difference between flexible and solid wedges?
A flexible wedge can accommodate limited alignment and thermal effects, while a solid wedge is more rigid. Selection follows the design and service conditions.
Bisa 316 Stainless Steel be used for every component in this wedge gate 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.
