As a dedicated manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for the global energy sector. Our High Pressure Pipeline Valve, engineered to API 6D standards, is a cornerstone for safe and efficient oil and gas transmission. Designed to withstand the most demanding pipeline conditions, this trunnion mounted ball valve offers superior sealing integrity, operational safety, and long-term durability, making it a trusted choice for critical infrastructure projects worldwide.
The core design of our trunnion mounted ball valve ensures exceptional performance under high pressure. Unlike floating ball designs, the ball is fixed on a trunnion, which significantly reduces the operating torque and minimizes seat wear, even during frequent cycling. This mechanism provides a double-block-and-bleed (DBB) capability as standard, enhancing isolation safety for maintenance operations. Key features and technical advantages include:
- High-Pressure Integrity: The valve is designed for ASME pressure classes from 150 to 2500, ensuring reliable containment in main transmission lines, gathering stations, and compressor stations.
- Fire-Safe Design (Optional): Available with fire-tested API 6FA/607 designs where metal secondary seals provide emergency shut-off in case of fire.
- Low Operational Torque: The trunnion support structure drastically lowers required actuation torque, allowing for smaller, more cost-effective actuators and reducing operational stress.
- Extended Service Life: Advanced seat materials like reinforced PTFE (RPTFE) or metal seats are selected for specific service conditions (e.g., sour gas, high temperatures), minimizing fugitive emissions and maintenance cycles.
- Versatile Actuation: Compatible with manual gear operators, as well as pneumatic, hydraulic, or electric actuators for remote or automated control, supporting modern SCADA systems.
- Full Bore Design: Minimizes pressure drop across the valve, preserving pipeline efficiency and reducing pumping costs over long distances.
The valve's construction adheres strictly to API 6D specifications for pipeline valves, covering design, manufacturing, and testing. Below is a summary of typical technical specifications:

Frequently Asked Questions (FAQ)
-
What is the main advantage of a trunnion mounted design over a floating ball design for high pressure?
The trunnion design anchors the ball, preventing it from shifting into the seat under pressure. This drastically reduces operating torque and seat wear, making it far more suitable for high-pressure, large-diameter applications common in transmission pipelines. -
Can this valve be used for sour gas (H2S) service?
Yes. We can supply valves with NACE MR0175/ISO 15156 compliant materials (e.g., specific grades of stainless steel) and appropriate trim to handle sour gas environments. Please specify this requirement during inquiry. -
What does "Double Block and Bleed (DBB)" mean in the context of this valve?
When the valve is closed, it provides two independent sealing surfaces (the upstream and downstream seats). A bleed port between them allows the trapped cavity pressure to be safely vented, confirming isolation and enabling safe maintenance. -
Do you offer fire-safe certification for these valves?
Fire-safe versions are available as an option. These valves are designed and tested to standards like API 6FA or API 607 to maintain sealing integrity for a specified time under fire conditions. -
What is the typical delivery lead time for a custom-sized valve (e.g., 36" Class 600)?
Lead times vary based on material, pressure class, and actuator selection. For standard material configurations, typical production time is 8-12 weeks. We provide accurate schedules upon receipt of detailed specifications. -
How do I select the appropriate seat material for my service (temperature, media)?
Selection depends on fluid composition, temperature, and pressure. PTFE/RPTFE suits most hydrocarbon services up to ~200°C. For higher temperatures or abrasive services, PEEK or metal seats are recommended. Our engineering team can assist based on your process data. -
Are your valves suitable for subsea or offshore applications?
While designed primarily for onshore transmission, we can discuss specific requirements for offshore use, including suitable materials, coatings, and extended testing protocols. Customization is available upon request. -
What testing is performed on each valve before shipment?
Every valve undergoes hydrostatic shell/seat tests per API 6D, using test pressures per ASME B16.34. Additional tests like fugitive emission testing (API 624/ISO 15848) can be performed as an optional requirement.
