Argus FK76M Trunnion Mounted Ball Valve
Overview
The Argus FK76M trunnion mounted ball valve is engineered to deliver long-lasting, tight shut-off performance in oil and gas, petrochemical, and chemical industry applications. It features a modular design that allows simplified adaptation to diverse safety, emissions, and performance requirements, and is available in standard and severe service designs with both metal-seated and soft-seated configurations for reliable sealing performance.
As an authorized supplier of Flowserve valve solutions, Seven Star LLC proudly offers the Argus FK76M to oil and gas, petrochemical, chemical, and power generation applications across the Sultanate of Oman, Muscat, and the wider GCC. Argus valves are known for performance and reliability in the world’s harshest and most demanding processes, delivering superior service lifetimes that minimize the need for maintenance shutdowns.
Measurement Principle
The FK76M features proven engineered elements that provide long service life with outstanding fugitive emissions performance and low operating torques even in the toughest applications, including a trunnion-mounted design, robust stem bearing system, spring-loaded seats with cavity relief, match-lapped balls and seats for bubble-tight performance, a true full bore, and a fully guided, anti-blow-out stem. Reliability is ensured by seat design to FCI 70-2 Class VI, enabling it to meet the highest demands with zero tightness.
Special and customized designs are available for ultimate high-cycle, high-temperature, and similarly challenging applications, with a stem supported in bearings that ensures seals remain free from operational loads. Special bearing configurations, including cladding of critical areas and trim coating configurations, further improve valve lifetime under extreme high-cycle service.
Engineering Design of the Argus FK76M
The FK76M is available in sizes from DN 65 to 900mm (NPS 2.5 to 36 inches) and pressure classes from PN 16 to 160 (ASME Class 150 to 900), designed for temperatures up to +1022°F (550°C) for the highest demands on valve tightness in both process and atmospheric (fugitive emission) service. These valves are designed to meet API 6D and ASME B16.34 requirements (API 608 on request), with fugitive emission compliance to ISO 15848 (API 641 on request) and fire-safe design to API 607 or ISO 10497.
Additional configurations include chambered ball seats and seat pocket body design for solid transport applications, process-optimized coatings and cladding options for severe service, flushing systems in critical valve areas to avoid media build-up, and high-performance oxygen service designs with in-house clean-room assembly and testing. Special alloys such as Inconel, Monel, Alloy 20, and Titanium are available for process and application-specific requirements, along with anti-static design per DIN EN ISO 17292 and functional safety (SIL) qualification.
