The Double Offset Advantage: Engineering for Absolute Sealing and Durability

Available throughout Turkey via its exclusive dealer LİNDER, the MATICA BV600 Series redefines reliability in flow control. Its core innovation—the double eccentric (double offset) shaft design—revolutionizes valve interaction. This precise engineering ensures the disc completely disengages from the seat seal within the initial degrees of rotation, eliminating destructive sliding friction. The result is bidirectional bubble-tight sealing, exponentially reduced seat wear, and exceptionally low operational torque. This translates directly to lower total cost of ownership, extended service life, and the ability to pair with more compact, economical actuators. Designed to conquer extreme challenges, the BV600 confidently manages aggressive chemicals, abrasive slurries, and a breathtaking temperature spectrum from cryogenic -196°C to intense +550°C.

Core Engineering Principles of the Double Offset Design

The double offset geometry is not merely a feature but the foundation of the valve’s superiority. The first offset of the shaft from the seat centerline and the second offset from the pipeline centerline create a cam-like motion. This motion guarantees a frictionless, smooth operation from the open to closed position, preserving the integrity of the sealing surfaces over thousands of cycles and ensuring consistent, leak-free performance even after prolonged inactivity.

Primary Industrial Applications of the MATICA BV600 Valve

The robust and versatile design of the BV600 series makes it the preferred solution for critical infrastructure and complex process industries across Turkey and beyond. Its application portfolio is extensive and critical to modern industry.

Oil, Gas, and Energy Production

From upstream extraction and midstream transmission to downstream refining, the BV600 ensures safe and reliable isolation. It is equally pivotal in power generation facilities, including thermal, nuclear, and renewable energy plants, for managing main steam lines, feedwater systems, and critical cooling circuits.

Heavy Process & Chemical Industries

In chemical, petrochemical, and pharmaceutical processing, where media can be highly corrosive or require absolute purity, the BV600’s advanced material and sealing options provide safe containment. The metallurgy, pulp, and paper sectors leverage its durability against abrasive and high-temperature media.

Infrastructure & Utilities

For municipal water supply networks, advanced wastewater treatment plants, and district heating/cooling systems, the valve offers long-term, maintenance-free operation. Its cryogenic capabilities make it indispensable for LNG terminals and processing facilities.

Technical Specifications and Configurations: BV600 Series

The BV600 is defined by rugged construction and precise engineering, allowing for extensive customization to meet exact project parameters and specifications.

Design Standards and Pressure Ratings

Engineered as a Double Offset High-Performance Butterfly Valve, it complies with international standards including API, ASME, and EN. The available size range extends from DN 50 (2″) to DN 1500 (60″), with pressure classes covering PN6 to PN100 and ASME Class 150, 300, and 600, ensuring compatibility with any pipeline design pressure.

Construction and Configuration Flexibility

The valve body is manufactured from high-integrity materials such as A216 WCB Carbon Steel or ASTM A351 CF8/CF8M Stainless Steel. Available in wafer, lug, and double flanged end types, it offers flexible integration into any piping configuration. Standard operating temperatures reliably reach up to +550°C with appropriate material selection.

Comprehensive Actuation Solutions

For optimal control integration, the BV600 series is compatible with a full suite of actuation technologies: manual lever and gear operation for simple control, and sophisticated pneumatic (double-acting or spring-return) or electric actuators for automated process integration and precise modulation within SCADA and DCS systems.

Advanced Sealing Technology: The Heart of Reliability

The true excellence of the BV600 is encapsulated in its customizable sealing systems, each engineered for specific service conditions and failure-mode protection.

Elastomer Seal Profiles (Type B & F)

Utilizing premium elastomers like Viton/FPM or EPDM combined with RTFE/PTFE soft seats, these profiles offer 100% bidirectional bubble-tight sealing. They feature self-sealing capability under vacuum, exceptional cycle life, and allow for easy in-line seat replacement, minimizing downtime.

Metal Seal (Type J)

Designed for ultra-high-temperature and abrasive services where elastomers are unsuitable. This system employs a flexible 316L stainless steel seat that exerts uniform pressure against the disc, providing robust, long-lasting sealing that meets ASME FCI 70-2 Class IV standards.

Fire-Safe Certification (API 607/6FA)

In critical safety environments, the fire-safe design ensures fail-safe operation. Under normal conditions, a primary soft seal guarantees tight closure. In a fire event, the secondary metal seat engages to maintain bidirectional sealing, preventing catastrophic escalation.

Detailed Material Selection for Optimal Performance

Every component of the BV600 can be tailored to the specific medium and operational environment, ensuring chemical compatibility and mechanical longevity.

• Valve Body: Carbon Steel WCB, Stainless Steel CF8/CF8M, Duplex, Super Duplex, and special alloys.
• Seat & Seal Systems: NBR, EPDM, VITON, PTFE, RPTFE, HYPALON, Metal (316L), and Fire-Safe combinations.
• Disc: Stainless Steel CF8/CF8M, with optional hard-facing (Stellite) for abrasive services.
• Stem: High-strength 17-4PH, SS316, Monel K500, or Duplex/Super Duplex steels (F51, F53, F55) for corrosion resistance and torsional strength.
• Bushings & Secondary Seals: Self-lubricating bronze or stainless steel bushings with PTFE/Graphite impregnation; Graphite packing for high-temperature stem sealing.
