KST APl 6D Trunnion Ball Valve

API 6D Trunnion-Mounted Ball Valve

• Nominal Size: 2″~36″, DN50-DN900 (Indicates the standard dimension used to identify a pipe or fitting)
• Nominal Pressure: CL150-CL2500, PN16-PN420 (Represents the maximum allowable working pressure that the valve can withstand)
• Actuation: Manual, pneumatic, electric, hydraulic, gas-liquid, etc. (Indicates the methods to operate the valve)
• Temperature Range:
  • Normal temperature: -29~120°C
  • High temperature: -29~180°C
• Valve Body: Carbon steel, heat-resistant steel, stainless steel, nickel-based alloy, cobalt-based alloy, etc.
• Application: Used in petroleum, petrochemical, and natural gas industries

Implementation Standards:

• Design and manufacturing standards: API 6D
• Face-to-face dimension standard: ASME B16.10
• Flange standard: ASME B16.5
• Inspection and test standards: API 6D

Explanation of Key Terms:

• Nominal size: The standard dimension used to identify a pipe or fitting.
• Nominal pressure: The maximum pressure a valve can withstand under specific conditions.
• Trunnion-mounted: The ball is supported by trunnions, allowing for better alignment and reduced friction.
• Actuation: The method of operating the valve, such as manually, electrically, or pneumatically.
• Valve body: The main part of the valve, typically made of metal.
