Core Advantages: Solving Your Most Critical Operational Pain Points
Zero Leakage Integrity for Pipeline Safety
One of the most persistent challenges in pipeline systems is fugitive emissions and leakage. The ODKV trunnion mounted ball valve addresses this with a trunnion-supported ball design that eliminates side loading on the seats, ensuring consistent sealing contact even under high pressure fluctuations. Our fire-safe design complies with API 607, providing a secondary metal-to-metal seal in the event of a fire, preventing catastrophic failure and protecting personnel and assets.
Extended Service Life in Harsh Environments
Forged steel construction delivers superior mechanical strength compared to cast valves, resisting fatigue, impact, and stress corrosion cracking. The blow-out proof stem design, combined with anti-static features, prevents stem ejection and mitigates electrostatic buildup—critical for applications handling flammable media like natural gas or refined hydrocarbons.
Reduced Operational Costs & Downtime
The double block and bleed (DB&B) functionality allows for safe isolation and venting of the valve cavity without removing it from the pipeline, simplifying maintenance and reducing downtime. The body cavity relief feature automatically equalizes pressure in the event of thermal expansion, protecting the valve from damage caused by trapped fluid.
Technical Details: Engineering Excellence
Material Science for Maximum Durability
Our forged steel bodies are manufactured from high-grade carbon and alloy steels, with optional stainless steel and nickel alloy variants for corrosive environments. The ball and stem are precision machined and hard-faced with Stellite® or Inconel to resist wear and galling, ensuring smooth operation over tens of thousands of cycles.
Seating Technology for Versatility
We offer a range of seat materials to match your application:
- Soft seats (PTFE/RPTFE/PEEK): Provide bubble-tight sealing for clean media at moderate temperatures.
- Metal-to-metal seats: Engineered for high-temperature, abrasive, or erosive services, with precision lapped surfaces for reliable sealing.
- Devlon® seats: Ideal for abrasive slurry applications, offering excellent wear resistance and chemical compatibility.
Trunnion Design for High Pressure Stability
Unlike floating ball valves, the trunnion mounted design uses a lower shaft to support the ball, reducing the torque required to operate the valve. This makes it ideal for large sizes and high-pressure classes, where manual operation with a gearbox remains feasible and efficient.
Application Scenarios: Where ODKV Valves Excel
Our forged steel trunnion mounted ball valves are specified for mission-critical applications across key industries:
- Oil & Gas Pipelines: Transmission and distribution of crude oil, natural gas, and NGLs, including offshore platforms and onshore gathering systems.
- Refining & Petrochemicals: Process lines handling corrosive chemicals, high-temperature hydrocarbons, and steam.
- Power Generation: Boiler feed water, steam lines, and flue gas desulfurization systems.
- LNG & Cryogenics: Low-temperature applications down to -196°C, with specialized materials for cryogenic service.
- Mining & Minerals: Slurry pipelines and process systems handling abrasive ore and chemical leachates.
Maintenance Convenience: Designed for Easy Upkeep
We understand that unplanned maintenance can derail project timelines and increase costs. The ODKV valve series is engineered for in-line maintainability:
- Top-entry design: Allows access to internal components without removing the valve from the pipeline, reducing labor and downtime.
- Modular construction: Seats, seals, and stem packing can be replaced quickly using standard tools.
- Lubrication ports: Optional seat lubrication and sealant injection systems enable on-site sealing enhancement without shutdown.
