Manual Trunnion Mounted Ball Valve Class 150~Class 2500 PN16-PN160 JIS 10K-20K

High-Quality Manual Forged Ball Valves (150~600LB): Industrial-Grade Solutions for High-Pressure Fluid Control

I. Core Attributes: Full-Specification Parameters and Performance Analysis

• Diameter Range: DN50~DN1000 (2″~40″), covering full-scenario requirements from medium-small industrial pipelines to large-scale pipe networks.
• Pressure Classes:
  • 150LB (PN20), 300LB (PN50), 600LB (PN110), with a maximum pressure rating of 10MPa (1450psi). Tested to API 598 standards, the shell undergoes a hydrostatic test at 1.5x nominal pressure, and the seal test at 1.1x nominal pressure to ensure zero leakage.

• Body Material: Constructed from A105 forged steel (ASTM standard carbon steel) with 0.35%-0.45% carbon content. The forging process eliminates metal segregation, offering a tensile strength ≥550MPa and yield strength ≥255MPa, suitable for -29°C to 425°C working conditions. The valve body, ball, and stem are forged from the same material to ensure integral structural strength and avoid welding stress concentration.
• Sealing System:
  • Seat Materials: Dual options of soft seal (PTFE) and metal seal (Stellite alloy/tungsten carbide). The soft seal is suitable for clean media ≤150°C, achieving API 598 Class IV leakage rate; the metal seal uses supersonic spraying with HRC60+ hardness, resistant to particle erosion and meeting API 6D Class VI (bubble-tight) leakage standards.

• Actuation: Standard manual operation with position indicator and locking device; optional worm gear drive (1:20 reduction ratio, operating torque ≤200N·m).
• End Connections: Flanged (RF/RTJ), butt weld (BW), socket weld (SW), and threaded (NPT/BSP) interfaces, compliant with ASME B16.5, ASME B16.25, and other standards.

• International Certifications: CE, ISO, DIN, API 6D, API 608, covering market access requirements in Europe, America, and Southeast Asia.
• Customization Services: Full-process OEM/ODM/OBM customization, including structural optimization, surface anti-corrosion treatment (e.g., epoxy coating), and brand logo engraving.
