Ball Valve

Starline Ball Valves are globally recognised for their superior forged body construction and unmatched mechanical integrity. Manufactured in Italy, Starline specialises in precision-engineered floating and trunnion-mounted ball valves built for high-pressure, high-temperature, and safety-critical applications. With over four decades of experience, Starline valves are trusted across energy, petrochemical, hydrogen, and offshore markets for their strength, reliability, and compliance with stringent international standards.

Key features and benefits.

Key Features

Starline valves are manufactured from a single forged block, enhancing structural integrity and resistance to stress, pressure, and temperature fluctuations. This results in a longer service life and superior performance in high-demand industrial environments.

Key Features

Available with soft or metal seats, and pressure ratings from ANSI 150 up to API 6A 10,000 PSI, Starline valves can be configured for everything from standard flow control to high-pressure isolation. Fire-safe and fugitive emission-certified options ensure compliance in safety-critical systems.

Key Features

All Starline Ball Valves come with ISO 5211 mounting interfaces, allowing quick connection to electric or pneumatic actuators. This makes them ideal for automated flow control in modern process plants and energy facilities.

Starline offers a comprehensive range of ball valve designs and pressure classes to suit a wide variety of demanding applications. The portfolio includes both floating and trunnion-mounted configurations, with options for full or reduced bore, and a selection of soft-seated, metal-seated, and fire-safe designs. Pressure ratings span from ANSI 150 up to API 6A 10,000 PSI, covering standard and high-performance needs. Popular series such as Standard Star, Super Star, Mega Star, Master Star, and Ultra Star provide tailored solutions across critical sectors. All Starline valves feature ISO 5211 mounting pads for direct actuator integration, making them fully compatible with automated systems.

Every Starline ball valve is engineered and manufactured to meet globally recognised standards, ensuring maximum safety, reliability, and compliance across critical applications. Certifications include API 6D, API 6A, and API 607 for fire-safe performance, along with PED, ISO 15848 for fugitive emission control, and ATEX for use in explosive environments. Many models are also SIL 3 capable, making them suitable for integration into safety instrumented systems. Full material traceability and comprehensive documentation are provided as standard, offering complete assurance for engineering teams and inspectors. Starline’s fully forged valve bodies deliver superior mechanical strength and a consistent grain structure—crucial for maintaining integrity under high-pressure, high-cycle, or thermally fluctuating conditions.
