ANSI API Ball Valve
ANSI API ball valves are high-performance shut-off valves designed according to ANSI and API standards for reliable flow control in oil, gas, petrochemical, and industrial piping systems. They provide tight sealing, durability, and safe operation under high pressure and temperature conditions.
Overview
ANSI API ball valves are quarter-turn valves that use a spherical ball with a central bore to control the flow of liquids or gases. Designed in accordance with ANSI and API standards, they are widely used in critical applications where safety, reliability, and performance are essential.
Design & Construction
- Quarter-turn ball valve design for quick open and close operation
- Full bore or reduced bore configurations available
- Flanged, threaded, or welded end connections
- Robust metal body suitable for high-pressure service
Standards & Compliance
- Manufactured in accordance with ANSI standards
- Designed to meet API valve specifications
- Suitable for inspection and testing as required by API standards
Operating Principle
- The ball rotates 90° to open or close the flow path
- When aligned, fluid flows freely through the bore
- When closed, the solid part of the ball blocks the flow completely
Applications
- Oil and gas production and processing
- Petrochemical and chemical plants
- Refineries and power generation facilities
- Industrial piping systems
Key Advantages
- Tight shut-off and reliable sealing performance
- Fast operation with minimal pressure drop
- High resistance to pressure, temperature, and corrosion
- Low maintenance and long service life
