Array Accuseal® Severe Service Valves for Critical Isolation in Process and Power Applications
The Array Accuseal® division of Array Holdings manufactures valve solutions for critical service requirements. Combining superior engineering design with state-of-the-art manufacturing facilities produces valves for a broad range of applications and service conditions. From extremely high temperatures, pressures and abrasive slurries to critical shut-off requirements associated with liquids pipelines and custody transfers, Accuseal offers the solution.
Critical-service metal-seated ball valves
Accuseal’s complete line of critical-service metal-seated ball valves are specifically designed for the harshest of applications associated with power, refining, petrochemical, synfuels, mining, and other process industries. The valves are ideally suited for services characterized by temperatures up to 750°C, abrasive / erosive slurries, pressures up to and exceeding ASME Class 4500, and high mechanical / thermal cycling requirements.
Valves are offered with either manual or automated operators. A complete range of sizes, classes and materials are available. All valves are designed and manufactured in Houston, Texas, US, incorporating significant technological and processing advancements. All of these factors, combined with exceptional customer service and responsiveness, make the Array Accuseal critical-service metal-seated ball valve the most advanced and reliable solution for severe service applications.
Double-block and bleed plug valves
Accuseal’s double-block and bleed plug valve combines field-proven designs with innovative features, making the valve more maintenance friendly and application versatile. The valve is ideally suited for tight shut-off requirements where dual block is required.
The ability to seal tightly from both directions simultaneously while bleeding the center cavity makes the Accuseal plug valve the best choice for critical isolation applications. Unique in the Accuseal valve is the ability to install a DTR system independent of the bonnet, thus allowing access to the internals of the valve without having to disassemble the DTR. A complete range of sizes and classes make the Accuseal your best DBB plug valve choice.
