What Are API 6A Ball Valves?

API 6A ball valves are a specific type of ball valve designed and manufactured to meet the rigorous standards outlined in API Specification 6A: “Specification for Wellhead and Christmas Tree Equipment.” This standard, published by the American Petroleum Institute (API), is a cornerstone for equipment used in the upstream oil and gas industry, particularly at the wellhead for controlling and containing high pressures and fluid flows.

Indra API 6A ball valves are built to handle exceptionally high pressures, ranging from 2,000 PSI up to 15,000 PSI, and a wide range of temperatures. They are essential for applications where conventional valves would fail due to the intense pressure and thermal demands.

Indra API 6A ball valves are available in all the design configurations as SB, SBB, DB and DBB, Floating and Trunnion types.

Key Features

API Specification 6A Compliance

Designed and manufactured to meet the full requirements of API Specification 6A — the industry standard for wellhead and Christmas tree equipment in the upstream Oil & Gas sector.

Exceptional Pressure Capability

Rated from 2,000 PSI up to 15,000 PSI, handling the extreme pressure conditions found at wellheads where conventional valves would fail.

All Design Configurations Available

Available in SB, SBB, DB and DBB configurations, and in both Floating and Trunnion types — covering all wellhead and Christmas tree installation requirements from a single supplier.

Wide Temperature Range

Designed to operate across a wide range of temperatures, ensuring reliable performance under the thermal demands of upstream wellhead service.

Configuration Options

Ball valves can be customized to meet your specific requirements:

Design

• Single Block (SB)
• Single Block & Bleed (SBB)
• Double Block (DB)
• Double Block & Bleed (DBB)

Type

• Floating
• Trunnion

End Connections

Applications

Ball Valves are the ideal choice for:

Wellhead equipment requiring compliance with API Specification 6A for upstream Oil & Gas service extraction from pressurized streams without process interruption

Christmas tree installations where extreme pressures up to 15,000 PSI demand purpose-designed valvesbiocides, or other chemicals into a live process stream

Upstream Oil & Gas applications where conventional valves would fail due to intense pressure and thermal demands contamination and ensure analytical accuracy design replaces separate valve assemblies

All DBB, DB, SBB and SB configurations for wellhead service — sourced from a single API 6A qualified manufacturer
