BRAND NEW ON FACTORY SKID
New ARGUS ball valve (Model FK76M). 4" size, 150 psi WOG. Constructed with Carbon Steel body with stainless steel trim for superior corrosion resistance. Flanged end connections. Air-Operated operation. Includes actuator assembly. New, never installed, and ready for immediate service. Made in United States.
This is a high-spec, fully automated 4" industrial ball valve package specifically engineered for severe service polymer and chemical processing applications. This complete assembly combines a top-tier Flowserve Argus FK79 Floating Ball Valve with a robust Flowserve Automax Supernova Pneumatic Actuator and premium control accessories. Because it is brand new on a factory skid and comes complete with Material Test Reports (MTRs) and all functional testing results, it represents a highly valuable, fully traceable, ready-to-install asset for critical piping systems.
- Technical Specification BreakdownPrimary Valve Assembly:Brand/Model: Argus (Flowserve) Model FK79
- Size & Rating: 4" Full Port (FP), Class 300 Raised Face (RF)
- Body Material: Carbon Steel (CS Body) with V4A stainless steel trim
- Seating Type: Metal-to-Metal Seats, designed to withstand extreme environments, thermal stress, and severe/abrasive media without degradation
- Application Focus: Purpose-built for high-viscosity or demanding media like polymers [
- Actuation System:Brand/Model: Flowserve Automax Supernova S250S08
- Type: Pneumatic Rack & Pinion Actuator
- Configuration: Spring Return ("S" Code), utilizing a heavy-duty concentric spring system to provide reliable mechanical failure positioning (fail-closed or fail-open)
- Control & Air Preparation Accessories:Positioner: Westlock Controls 360-NBY2B2M0600 positioner for exact throttling or position feedback
- Solenoid Valve: ASCO EF8003G1 explosion-proof/severe service solenoid valve
- Air Control: ROSS EAC (Exhaust Air Controller) for controlled stroking speeds
- Filter/Regulator: IMI Norgren Excelon B74G-4AK-AD3-RMN high-flow filter regulator to ensure a clean, steady instrument air supply
- Commercial & Asset HighlightsFull Traceability: The presence of MTRs (Material Test Reports) and original testing records is a critical commercial asset. This allows the assembly to be integrated immediately into strictly regulated plants (such as refinery, chemical, or pharmaceutical facilities) that require documented validation of metallurgy and pressure testing.
- Turnkey Condition: Being brand new on a factory skid means the unit has been protected from environmental wear, the seals remain uncompromised by operational cycling, and the integration work (mounting the actuator, piping the positioner, and wiring accessories) was done in a controlled factory setting rather than in the field.
