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 across widely different process specifications, 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 on lines that cannot be taken offline lightly.
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 for minimal pressure drop and pigging compatibility, 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 where a standard commercial-grade valve would fail prematurely, 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, reducing the frequency of unplanned maintenance interventions.
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.

The Argus FK76M combines a modular trunnion-mounted design with extensive severe-service configurability. Core capabilities include:
- Metal-seated or soft-seated configurations for reliable sealing across applications.
- Seat design to FCI 70-2 Class VI for zero-tightness shutoff.
- Size range DN 65-900mm; pressure class PN 16-160 (ASME 150-900).
- Operating temperature up to +1022°F for extreme process and FE demands.
- Fugitive emission compliance to ISO 15848; fire-safe to API 607/ISO 10497.
- Trunnion-mounted design with fully guided, anti-blow-out stem.
- Special alloy options: Inconel, Monel, Alloy 20, Titanium.
- API 6D and ASME B16.34 compliant; SIL functional safety qualified.
Industrial Applications
The Argus FK76M is well suited to oil and gas, petrochemical, and chemical facilities across Oman requiring critical shutoff performance in the harshest process conditions. Its extreme temperature rating, fire-safe design, and configurable severe-service options make it dependable for pipeline, refinery, and processing applications throughout the region, including oxygen and high-cycle solid transport services.

Why Choose Seven Star LLC for Severe-Service Ball Valve Sourcing
A trunnion-mounted ball valve rated to fire-safe and fugitive-emission standards is only as good as the seat material and cladding configuration selected for the actual process service – a metal-seated valve specified for a duty that only needed a soft seat adds unnecessary cost, while the reverse leaves a valve vulnerable in high-cycle or abrasive service. Seven Star LLC’s engineers review the process fluid, cycle frequency, and emission-compliance requirements (ISO 15848, API 641) with the customer before the FK76M is ordered, confirming seat class, special alloy needs, and fire-safe certification against the actual pipeline or refinery duty. We also help plan spare seat and seal kits given the valve’s extreme operating range, and coordinate delivery around planned pipeline and refinery turnarounds across Muscat, Sohar, and the broader GCC.
