In-House Starline Manufacturing

Factory-approved and licensed UK manufacturing delivering fully traceable, precision-built Starline ball valves with fast-track availability.

ACV provides dedicated access to Starline’s specialist forged steel valve manufacturing, delivering high-integrity ball valves engineered for performance, durability, and complete material traceability. Manufactured in Europe using fully certified materials and proven forging processes, every Starline valve is built to withstand demanding service conditions and maintain long-term sealing integrity.

Through our in-house Starline manufacturing support and close partnership with the factory, we offer fast-track build schedules, custom trim options, bespoke configurations, and full documentation packages tailored to your project requirements. Whether you need specific materials, cryogenic preparation, extended stems, specialist seats, or project-specific upgrades, every valve is assembled, tested, and certified to the highest standards.

With extensive UK and European stockholding backed by a global supply network, we help you reduce lead times, secure consistent availability, and receive Starline valves that are correctly manufactured, fully compliant, and ready for immediate installation.

Our Process

Our Starline manufacturing process ensures every ball valve is produced with precision, consistency, and full material traceability. From raw material selection to final inspection, each stage is tightly controlled to deliver reliable performance for critical industrial applications.

Material Sourcing & Preparation

Starline source fully European-forged materials under strict traceability controls. Each forging is verified for compliance before entering production, ensuring consistency and integrity from the very first stage.

CNC Machining

Forgings are precision-machined using advanced CNC technology to achieve exact tolerances and critical dimensions. Every component is produced to deliver repeatable quality and high-performance functionality across all valve designs.

CNC Machining

Using advanced CNC equipment, bodies, end connections, stems, balls, and internal components are precision-machined to exact tolerances. Each part is produced to deliver uniform, repeatable performance across the full manufacturing batch.

Assembly

Machined components are assembled by skilled technicians following controlled procedures. Seats, seals, stems, and internal components are fitted with exacting care to deliver smooth, reliable operation.

Testing

Each valve undergoes hydrostatic, pneumatic, and functional testing to verify tight shut-off, integrity, and performance. Test procedures follow proven Starline methodologies to ensure every unit meets the required operational standards.

Surface Treatment & Finishing

External surfaces receive protective coating and finishing processes designed to deliver longevity, corrosion resistance, and long-term reliability in demanding environments.

Final Inspection

Completed valves are inspected against drawings, specifications, and customer requirements. This includes dimensional checks, compliance verification, and documentation reviews to ensure full traceability and readiness for dispatch.

Packing & Dispatch

Valves are securely packed and labelled, complete with documentation and certifications. ISPM15-certified cases are available for export, ensuring safe, compliant transport to global project locations.

FAQs

Each valve is supplied with full documentation including material certificates, inspection reports, pressure test records, QC sheets, torque values (if automated), and complete Manufacturing Record Books (MRBs). Project-specific documentation formats can be provided to meet EPC, end-user, or audit requirements.
