Designed for Maximum Strength and Leak-Proof Operation

Our fully welded ball valves are designed for the most demanding industrial applications, providing superior performance where leak prevention, high-pressure capability, and long-term reliability are critical. These valves feature a fully welded body construction, eliminating the need for flanges, bolts, and threaded connections, thereby maximizing structural integrity and minimizing potential leak paths. The forged steel construction ensures a uniform fine-grain structure and exceptional toughness, making these valves ideal for critical piping systems where any failure is unacceptable.

Engineered with Advanced Welded Construction Technology

The fully welded design represents the pinnacle of valve engineering, with the valve body welded together from two parts using a precise automated welding process. This permanent sealing structure eliminates the most common external leakage sources found in bolted or flanged designs. The compact spherical design not only reduces overall size and weight but also provides maximum resistance to pipeline pressure and stress. These valves are available in both floating and trunnion configurations, providing bidirectional bubble-tight sealing performance under various operating conditions.

Delivering Unmatched Performance and Reliability

Our fully welded ball valves are designed to withstand extreme pressure and temperature conditions, with pressure ratings ranging from Class 150 to Class 2500 LB (PN16-PN420) and a temperature range of -46°C to 200°C. Spring-loaded seats ensure tight sealing even at low pressures, while the pressure-assisted design enhances sealing performance as line pressure increases. These valves are available in sizes ranging from 2 inches to 60 inches (DN50-DN1500) and in full bore or reduced bore configurations to meet specific flow requirements. Fire-safe design conforming to API 607 standards ensures continued operation even in fire situations, while anti-static and anti-blowout stem designs provide additional safety features.

Built for Critical Industrial Applications

Fully welded ball valves are the industry standard for applications where reliability and safety are paramount. They are widely used in oil and gas transmission pipelines, natural gas distribution systems, petrochemical plants, power generation facilities, and offshore platforms. These valves are particularly suitable for long-distance buried pipelines, underground facilities, and subsea applications where maintenance opportunities are limited and preventing leaks is critical. The welded construction makes them ideal for pipeline pigging operations and high-pressure gas transmission services.

Manufactured to Rigorous International Standards

Our fully welded ball valves comply with API 6D, ASME and ISO standards. Each valve undergoes rigorous testing in accordance with API and ISO standards to ensure leak-tight sealing and long-term reliability. These valves offer various connection options, including flanged, butt-welded, or hub connections, for easy integration into existing piping systems. Extended stem options and multiple actuation methods (manual, pneumatic, electric, or hydraulic) are available to meet diverse operational requirements.
