In petrochemical processing systems, valves are required to provide reliable isolation under high pressure, elevated temperatures, and demanding fluid conditions. A Petrochemical Side-Entry Ball Valve provides a practical solution for critical pipeline and process isolation where dependable shutoff and bidirectional sealing are required.
Platinum Valve's side-entry ball valves are manufactured in accordance with API 6D and feature a solid double-trunnion configuration with two independent seats. This design supports reliable bidirectional sealing and can be configured for demanding petrochemical services.

Side-Entry Trunnion Ball Valve Design
The side-entry configuration provides access to the internal valve components through a bolted body construction. The valve can be manufactured in forged or cast designs with two-piece or three-piece bolted bodies.
Unlike a floating ball design, the trunnion-mounted ball is supported at both ends. This configuration helps manage the mechanical load on the ball and supports operation in high-pressure applications.
The valve uses two independent seats, allowing sealing from either direction. Depending on project requirements, the seat configuration can include soft seats, metal seats with hard-facing, double-piston seats, or combination seats.
Performance for Petrochemical Service
Petrochemical pipelines and process systems can handle hydrocarbons, chemicals, and other demanding media. Valve materials and sealing arrangements therefore need to match the operating environment.
The side-entry ball valve can be supplied with different material options, including:
Carbon steel
Stainless steel
Low-temperature carbon steel
Duplex stainless steel
Super duplex
Inconel
For more aggressive environments, CRA overlays can be applied to dynamic sealing areas or wetted parts. These material and surface-treatment options allow the valve configuration to be adapted to specific project requirements.
High-Pressure and High-Temperature Applications
The valve range is designed for a broad range of pressure and temperature conditions. Available pressure classes extend from ASME 150 to ASME 2500, while the specified temperature range is -150 to 662°F (-101 to 350°C).
This makes the side-entry trunnion ball valve suitable for various isolation duties within petrochemical facilities, including applications where pressure con
