Constructed with an unrivaled level of precision, the ball and seat within these valves are fortified with innovative hard coatings, employing chrome carbide or tungsten carbide. This exceptional layer of protection grants superior resistance to both erosion and abrasion, significantly boosting durability and dependability.
Our state-of-the-art SNT High Performance Soft Seated Ball Valves integrate a revolutionary HVOF coating system. Each valve is subjected to meticulous mate-lapping through custom techniques, ensuring an impeccable 100% sealing. The groundbreaking live loading feature guarantees zero emissions and keeps the ball in constant contact with the seat, efficiently sweeping away contaminants. This avant-garde self-cleaning mechanism averts interference and damage from particles, making these valves an ideal solution for slurry and abrasive service applications.
Ingenious anti-blowout design reliably prevents stem ejection, safeguarding against potential damages and ensuring operational integrity.
The seat ring architecture, featuring wave springs and dual-scrapers, efficiently cleans the ball surface and ensures impeccable sealing performance.
Our advanced dual-sealing mechanism ensures superior leakage control by strategically preventing flow contact with the spring, thus ensuring leakproof performance.
The innovative draining and sweeping design effectively prevents valve jamming by maintaining cleanliness throughout its operation.
Designed in strict accordance with API 607 standards, our valves offer robust fireproof and anti-static functionalities, assuring safety and dependability.
Their Outstanding Features Include:
A streamlined, elegant design ensures effortless disassembly and simplicity.
Crafted with a keen focus on maintenance, our ball valves incorporate a non-tight fit design, facilitating swift servicing and minimizing downtime during regular maintenance schedules.
Incorporating cutting-edge sealing technology, our valves offer unrivaled security and peace of mind.
The ingenious multi-layer sealing between the stem and body provides dual protection with a combination of O-ring and graphite/PTFE, guaranteeing an exceptional sealing performance under demanding conditions.
This state-of-the-art design adheres to the stringent TA-Luft/Shell SPE 77/312 standards, ensuring uncompromised quality and safety.
Extended Service Life for Superior Cost-Efficiency
Through advanced processing techniques such as spray welding, spraying, and fusion welding, our metal seated ball valves achieve a remarkable hardness range of HRC58-73 and a binding force of 80-40MPa. With an on-off cycle lifespan that exceeds 100,000 operations and a leakage class of ANSI VI, they ensure superior longevity and cost-efficiency.
Modular Design for Enhanced Convenience
Our modular inner sealing design ensures effortless interchangeability between soft and metal seats, delivering flexibility, reliability, and user-centric convenience.
