High-Performance Seat Supported Ball Valve for Oil & Gas Pipelines API 6D
Product Description
Our Seat supported Ball Valve, specifically engineered for critical industrial applications, is a robust floating ball valve designed for superior sealing and long service life in demanding environments. Primarily serving the oil, gas, and petrochemical sectors, this valve is ideal for isolation and control services in Middle Eastern refineries, processing plants, and pipeline systems. Its design ensures reliable performance under high pressure and variable temperatures, making it a trusted component for mission-critical operations.
Key Features & Benefits
The design of our Seat supported Ball valve incorporates essential safety and operational features required by modern industry standards:
-
Enhanced Safety & Integrity: Features a fire-safe design compliant with API 607, an anti-static system, and a blowout-proof stem for maximum operational safety.
-
Reliable Sealing: The double block and bleed (DBB) capability, often with an optional double ball design, provides positive isolation. The self-relieving seat cavity prevents dangerous pressure build-up.
-
Low Emissions: Optional fugitive emission testing ensures compliance with stringent environmental regulations, reducing methane and VOC leaks.
-
Durable Construction: Available in full or reduced bore with two or three-piece body structures. Built to major international standards including API 6D, ASME, and DIN.
-
Operational Flexibility: Supports various connection ends (RF, RTJ, BW, NPT) and can be operated manually or via electric, pneumatic, or hydraulic actuators.
This robust Seat supported Ball Valve is built to withstand the harsh conditions typical of Middle Eastern oil and gas operations.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of a Seat supported Ball valve design?
A: The key advantage is reliability and reduced stress on the ball. In a Seat supported Ball Valve, the seats fully support the ball, ensuring stable alignment and reducing wear, which leads to a longer cycle life and consistent sealing performance.
Q2: Is this valve suitable for fire-safe applications?
A: Absolutely. Our valve is designed and tested to API 607/ISO 10497 fire-safe standards, ensuring secondary metal sealing in the event of a fire, which is crucial for oil and gas facilities.
Q3: Can this valve be used for Double Block and Bleed (DBB) service?
A: Yes. The standard design offers true DBB capability. For higher integrity isolation, an optional double ball design is available, providing an additional safety barrier for maintenance and bleed-down procedures.
Q4: What makes this valve suitable for the Middle Eastern market?
A: It is constructed from corrosion-resistant materials (like SS and DSS) suitable for sour service, meets all key API standards demanded by the regional oil industry, and its robust design handles high temperatures and sand-laden environments effectively.
Q5: Are emission controls available?
A: Yes. We offer optional fugitive emission testing and packing systems compliant with ISO 15848 or TA-Luft standards, helping plants meet environmental and regulatory requirements for low-emission operation.
For reliable isolation in your pipeline systems, our engineered Seat supported Ball Valve provides the safety, durability, and compliance needed for your critical applications.
