Reliable Flow Control: 2-Piece Trunnion Ball Valve Built to API 6D

For industries where flow control must be precise, safe, and fully compliant with international standards, the API 6D 2-Piece Trunnion Ball Valve is a trusted solution. Designed with durability and performance in mind, this valve is ideal for critical applications across the oil & gas, petrochemical, and power generation sectors. Its robust two-piece bolted construction, combined with a range of pressure classes and safety features, ensures long-term reliability in demanding environments.

Key Features

· Two-Piece Bolted Body Construction  

 The valve features a flanged-end, two-piece bolted design, offering ease of installation, maintenance, and internal inspection without compromising strength.

· Trunnion-Mounted Ball Design  

 Ideal for high-pressure environments, the trunnion ball design minimizes operating torque and provides stable sealing across a wide pressure range.

· Blowout-Proof Stem  

 An anti-blowout stem design enhances safety during maintenance and operation, preventing stem ejection under pressure.

· Fire-Safe Construction  

 Equipped with graphite fire-safe rings, the valve provides an additional layer of protection against external leakage in fire conditions.

· ISO 5211 Mounting Pad  

 A standard ISO 5211 mounting pad allows for easy automation with electric or pneumatic actuators, simplifying integration into automated systems.

Materials and Construction

· Body and Adapter Material: Carbon Steel WCB  

 Known for its strength and durability, WCB is a widely used material suitable for a range of process fluids and temperature conditions.

· Flange Connection: In compliance with ASME B16.5 standards, ensuring compatibility with global piping systems.

Pressure Class Options

To suit a variety of operational requirements, the valve is available in the following ANSI pressure classes:

· Class 150

· Class 300

· Class 600

These options give engineers and operators the flexibility to select the right valve for system pressures and conditions.
