Industrial pipeline systems require reliable valves to control and isolate fluid flow under different pressure, temperature, and media conditions. When a pipeline project involves large diameters or demanding operating environments, valve selection becomes especially important because the valve needs to provide dependable sealing and reliable operation throughout its service life.

Side-entry trunnion ball valves are widely used for critical isolation services because their construction supports bidirectional sealing and stable operation under demanding conditions. With large size options, multiple pressure classes, and a range of material and configuration choices, this valve design can be adapted to different industrial pipeline requirements.

Why Side-Entry Trunnion Ball Valves Are Used for Pipeline Isolation

One of the main applications of side-entry trunnion ball valves is pipeline isolation. In industrial systems, valves may need to completely isolate a section of piping during normal operation, inspection, maintenance, or emergency situations.

A trunnion-mounted ball valve uses a solid double-trunnion configuration with two independent seats. This arrangement supports bidirectional sealing and makes the valve suitable for critical isolation duties where reliable shutoff is required.

For large pipeline systems, these characteristics make side-entry trunnion ball valves a practical option when dependable isolation is a key requirement.

Side-Entry Trunnion Ball Valves in Oil and Gas Pipelines

Oil and gas pipelines often require valves that can operate under high pressure and demanding service conditions. Isolation points throughout these systems need reliable sealing to help operators control and separate different sections of the pipeline.

Side-entry trunnion ball valves can be used for these isolation duties, particularly when a project requires large valve sizes, high pressure ratings, and bidirectional sealing.

Platinum Valve's Side-Entry Trunnion Ball Valve is manufactured in accordance with API 6D. The product range covers sizes from NPS 1 to NPS 56 (DN 25–1400) and pressure ratings from ASME Class 150 to ASME Class 2500, providing options for both conventional and large-diameter pipeline systems.

Natural Gas Pipeline Applications

Natural gas pipelines place particular importance on valve sealing and operational reliability. The valve may need to maintain tight shutoff while operating under elevated pressure and temperature conditions.

The side-entry trunnion ball valve from Platinum Valve includes features intended for demanding isolation applications, such as a double block and bleed (DBB) design, secondary pure graphite seals, an anti-static device, and an anti-blowout stem. Emergency sealant injection is also available at the seats and stem.

For applications where fugitive emissions need to be controlled, low-fugitive-emission stem packing is available. Fugitive-emission testing in accordance with ISO 15848 is also offered as an option.

Petrochemical and Chemical Pipeline Services

Petrochemical and chemical facilities may transport fluids with corrosive, abrasive, or otherwise demanding characteristics. In these applications, valve materials and sealing configurations need to be selected according to the actual operating conditions.

Platinum Valve's side-entry trunnion ball valve is available in materials including carbon steel, stainless steel, low-temperature carbon steel, duplex, super duplex, and Inconel. Material selection can also be customized according to project requirements.

For applications requiring additional protection, CRA overlay is available on dynamic sealing areas or wetted parts. The valve can also be configured with soft or metal seats, while hard facing is available for the ball and seats. Double-piston and combination seat configurations provide additional options for different service conditions.

Large-Diameter Pipeline Requirements

As pipeline diameter increases, valve selection needs to take into account the pipeline size, pressure class, temperature, connection requirements, and service medium.

Platinum Valve's side-entry trunnion ball valve is available up to NPS 56 (DN 1400), making it an option for large-diameter pipeline projects. The listed temperature range is -150 to 662°F (-101 to 350°C), with pressure ratings from ASME Class 150 to ASME Class 2500.

The valve body can be supplied in forged or cast construction, with bolted two-piece or three-piece designs. End connection options include RF and RTJ connections according to ASME B16.5 and B16.47, butt-welded connections according to B16.25, socket-welded connections according to B16.11, and hub connections.

These options allow the valve configuration to be matched with different pipeline installation requirements.

Side-Entry Trunnion Ball Valves for Critical Isolation

For critical pipeline applications, sealing performance is an important part of the overall valve design. A valve may need to provide dependable isolation while supporting operational safety and maintenance requirements.

The side-entry trunnion ball valve from Platinum Valve combines two independent seats with a solid double-trunnion configuration to support bidirectional sealing. The DBB design provides an additional isolation function, while secondary graphite seals, an anti-blowout stem, and optional emergency sealant injection provide further configuration choices for demanding services.

The valve can be operated manually using a wrench or gear with padlocking, or supplied with pneumatic, hydraulic, or electric actuation. This allows the operating method to be selected according to the pipeline system.

What to Consider When Selecting a Side-Entry Trunnion Ball Valve

Selecting a large-diameter side-entry trunnion ball valve should start with the actual operating requirements of the pipeline.

Valve Size

The valve size should match the pipeline configuration and required flow passage. For large pipeline projects, the available size range is an important consideration.

Pressure Rating

The selected pressure class should correspond to the pipeline's design pressure and applicable specifications. Platinum Valve offers this valve from ASME Class 150 through ASME Class 2500.

Operating Temperature

Temperature affects the selection of materials, seats, seals, and other components. The listed temperature range is -150 to 662°F (-101 to 350°C), depending on the selected configuration.

Valve Materials

The transported medium and surrounding conditions should be considered when selecting valve materials. Carbon steel, stainless steel, low-temperature carbon steel, duplex, super duplex, and Inconel provide different options for project requirements.

Seat and Sealing Configuration

Soft seats, metal seats, hard facing, double-piston seats, and combination seats can be selected according to the pipeline medium and operating conditions.

End Connection

RF, RTJ, butt-welded, socket-welded, and hub connection options allow the valve to be matched with different pipeline connection requirements.

Standards and Testing

For critical pipeline applications, recognized design and testing standards are an important part of valve selection.

Platinum Valve's side-entry ball valves are manufactured in accordance with API 6D. Compliance with API 6D, ISO 5208, and API 598 inspection and testing requirements is also available.

Additional testing and certification options include API 607 fire-safe testing, IEC 61508 SIL 3 certification, ISO 15848 fugitive-emission testing, and PED 2014/68/EU. The applicable standards and certifications can be selected according to the requirements of a specific pipeline project.
