Brief introduction
Product name: Forged steel fully welded ball valve
DN: 2"(50)~ 56"(1400)
CLASS(PN): 150LB(PN16)~1500LB(250)
Application Standard
Pressure temperature class: ASME B16.34
Design: ASME B16.34, API 6D, GB, GOST, DIN, BS,etc.
Test: API 6D / API 598 / GB / T 13927 and other relevant national standards.
Structure length: API 6D, ANSI B16.10, GB 12221, GOST, DIN, BS / manufacturer standard / user requirements.
Connection end: BW (ASME B16.25, ASME B31.8 / GB / T12224 and other national standards), RF (ASME B16.5, ASME B16.47, GB / JB / HG / GOST, DIN, etc.), RTJ (ASME B16. 5, ASME B16.47, GB / JB / HG / GOST, DIN, etc.), BW + PUP (the length of the transition tube is customized)
Fire protection requirements: API 607/API 6FA/BS 6755
Anti-static electricity: API 608/BS 5351
Valve anti-sulfur: NACE MR. 0175
Structural features
Body structure: Bolted body, forged steel
Valve seat: Self-Relief / Double Piston Effect Seat / Upstream Self-Relief Valve Seat Downstream Double-Piston Effect Seat (Optional)
Ball: Trunnion mounted,solid
Flow pass: Full bore/ reduced diameter (optional)
Valve stem: Anti-blowout, can be lengthened (optional)
Support: The upper and lower support structure, the valve stem is not subject to radial bending moment, only bears the torque, and the switching torque is light.
Operation mode: Manual / electric / pneumatic / pneumatic-hydraulic linkage / electro-hydraulic linkage / hydraulic (optional)
Seal: Soft seal / metal seal / composite seal (primary metal seal + secondary soft seal)

Locking device: Optional
Leak rating: Soft seal: ISO 5208 Class A, metal seal: ISO 5208 Class C or
higher, ANSI VI
MOC
Product advantages
The valve body adopts forged steel and fully welded structure, which eliminates the casting defects of the casting and prevents any possible leakage. It is especially suitable for the working conditions of long-distance oil and gas pipelines.
