High-Performance Fixed Ball Valve for Oil & Gas Pipelines – API 6D, Fire-Safe
Product Introduction
Our Fixed Ball Valve is engineered for critical isolation and control applications in the oil, gas, and petrochemical industries, particularly in demanding Middle Eastern markets. Designed to meet the highest international standards, this robust valve ensures reliable performance, zero leakage, and long-term safety in refinery, pipeline, and plant operations. The fixed ball valve design provides stable operation under high pressure and temperature fluctuations, making it the preferred choice for mainline and emergency shutdown services.
Key Features & Benefits
Superior Sealing & Safety: Features a Double Block and Bleed (DBB) function. The advanced seat design ensures bidirectional sealing, while the anti-blowout stem and fire-safe construction (API 607 certified) guarantee safety in extreme conditions.
Reliable Construction: Available in two-piece or three-piece body designs (full/standard bore). The fixed ball valve mechanism minimizes seat wear and provides low operating torque. The anti-static device and cavity pressure auto-relief feature enhance operational safety.
Zero Emission Commitment: Optional fugitive emission testing ensures compliance with stringent environmental regulations, preventing process fluid leakage into the atmosphere—a critical requirement for modern plants.
Extended Service Life: Manufactured from certified forgings/castings (carbon steel, stainless, duplex, low-temp carbon steel, alloy, Inconel, Monel, Aluminum Bronze), ensuring excellent corrosion resistance and durability in harsh desert and offshore environments.
Flexible Operation & Connectivity: Supports manual, pneumatic, electric, or hydraulic actuation. Connects via RF, RTJ, FF, or BW ends per ASME/DIN standards, ensuring easy integration into existing pipelines.

FAQ
Q: Why choose a fixed ball valve over a floating design for mainline service?
A: The fixed ball valve is superior for larger sizes and higher pressures as the ball is trunnion-mounted, reducing seat load and torque. This ensures longer seat life, more reliable sealing, and easier operation in critical 24/7 applications like oil transmission lines.
Q: How does the fire-safe design protect my operation?
A: Our fixed ball valve complies with API 607/6FA. In a fire event, special graphite seals and metal seat rings maintain a seal even if soft seals are damaged, preventing catastrophic fluid release and containing the hazard.
Q: Are your valves suitable for sour gas (H2S) service?
A: Yes. We provide fixed ball valves in NACE MR0175/MR0103 compliant materials like duplex stainless steel or specially treated alloys, suitable for sour environments common in Middle Eastern oil and gas fields.
Q: Can you provide certified valves for a specific project?
A: Absolutely. We supply fully documented valves with traceable materials, 3.1 material certificates, and comprehensive test reports (pressure, fire, fugitive emission) per API 6D, meeting major EPC and operator specifications in the Gulf region.
