API6D Flanged Ball Valve 2-PC Stainless Steel Class 300

Key Features

• Class 300 Configuration: Intended for piping specifications requiring this pressure class. Selection should use the complete valve’s approved pressure–temperature rating, including limitations imposed by the seats and seals.
• Full-Bore Flow Path: The open passage helps limit obstruction across equipment connections. Confirm flow capacity and allowable pressure loss for the selected size.
• Two-Piece Construction: Separate body sections permit internal inspection and servicing after isolation, depressurization and appropriate dismantling.
• ASME Connection Dimensions: Raised-face flanges reference ASME B16.5, while installation lengths reference ASME B16.10. Verify the Class 300 connection details against the mating equipment.
• Automation Interface: An ISO 5211 mounting flange supports actuator integration. Sizing should consider maximum differential pressure, operating torque, cycling frequency and required stroke time.

Materials and Construction

Listed body and end-cap options include CF8, CF8M and CF3M. The ball, stem, gland and listed fasteners are stainless steel. Seats, joint gasket, thrust washer and packing are PTFE.

Confirm component grades individually and assess their compatibility with the process fluid, contaminants and cleaning chemicals.

Typical Applications

• Process Piping: Compatible liquid and gas lines governed by a Class 300 piping specification.
• Pump and Equipment Packages: Isolation where design conditions and equipment connections require the selected pressure class.
• Chemical Processing: Duties supported by a confirmed alloy and sealing-material assessment.
• Oil and Gas Facilities: Selected process and auxiliary services meeting the project’s technical requirements.
• Industrial Utilities: Compatible services where the design pressure–temperature conditions justify Class 300 selection.

Pressure and Installation Selection

Assess design pressure, operating temperature, maximum differential pressure and potential transient conditions before selecting the valve. Body pressure class alone does not establish the operating limits of the PTFE sealing components.

For replacement projects, confirm flange dimensions, bolting, gasket requirements and face-to-face length. A Class 300 valve should not be treated as a direct dimensional replacement for a Class 150 valve.

Provide suitable pipe support and access for operation, actuator removal and future maintenance. Use the valve primarily for on/off isolation; prolonged partial opening requires a separate assessment of seat wear and flow conditions.

Documentation and Optional Configuration

API 6D is the published design reference. Specify the applicable edition, inspection scope and required material and test records in the purchase documentation.

A fire-safe version is listed as an option. Confirm qualification and sealing construction for the offered configuration. Any API Monogram requirement should be verified against the manufacturer’s current licence and product scope.
