Q1 Journey to the Middle East: Empowering Infrastructure in Kuwait

Client: AL-ARFAJ ENGINEERING CO. W.L.L

Project Location: Kuwait Free Trade Zone, Kuwait

A key commercial and industrial hub across the Gulf region, Kuwait Free Trade Zone imposes stringent requirements on structural integrity, corrosion resistance, and operational reliability for large-diameter fluid control equipment.

Industrial operations across the Middle East are characterized by high ambient temperatures, arid climate, and demanding continuous operating cycles. After thorough technical assessment and qualification review, the end client AL-ARFAJ ENGINEERING CO. W.L.L selected SJ as its primary valve supplier. Tailored for this large-scale infrastructure project, the SJ engineering team delivered high-performance large-size butterfly valves built to withstand harsh process media and local environmental constraints.

Q2 In-depth Analysis: Core Specifications and Advantages of SJ Butterfly Valves

Parameter Item            Specification / Data

Equipment Name:            Butterfly Valve

Pressure Rating:              10 Bar

Size (NPS):               54" (DN1350)

End Connections:            RF (Raised Face)

Body Material:             DI (Ductile Iron)

Disc Material:          CF8M (SS316 Stainless Steel)

Stem Material:              17-4PH

These 54-inch butterfly valves incorporate SJ’s proven fluid-control technology with standout advantages:

Robust Construction & Structural Integrity (DI Body + CF8M Disc): The 54” large-size design features a heavy-duty ductile iron body paired with a corrosion-resistant CF8M (316SS) disc. It accommodates high-flow fluid transfer while delivering excellent resistance to pitting corrosion and localized wear under severe service conditions.

High-Strength Stem for Stable Torque Transmission (17-4PH) Fitted with a 17-4PH precipitation-hardened stainless steel stem, the valve offers superior torsional and bending strength, guaranteeing stable long-term torque transmission under heavy operating loads.

Bubble-Tight Sealing Performance (NBR Seat): Precision-machined NBR resilient seat achieves reliable bubble-tight shut-off. It provides outstanding leak-tight performance, alongside good resistance to oil media, abrasion, and cyclic mechanical fatigue.
