Product Description
Discover our premier series of Zero-Leakage ball valves, designed to triumph in demanding service applications where high temperature and high pressure are the norms. Engineered for excellence, these valves promise unparalleled reliability and performance.
Our ball and seat components are meticulously enhanced with hard coatings of either chrome carbide or tungsten carbide. These remarkable materials offer superior erosion and abrasion resistance, ensuring long-lasting durability and efficient operation.
At SNT Machinery, we employ an advanced HVOF coating system and apply a specialized mate-lapping technique developed in-house. This ensures 100% sealing efficiency, bolstered by live loading that guarantees zero emissions. The innovative design keeps the ball in constant contact with the seat, effectively wiping away contaminants. This self-cleaning action safeguards the valve against interference and damage from foreign particles, making it exceptionally suitable for both slurry and abrasive service applications.
Our Advantages
SNT Ball Valves are meticulously crafted to adhere to a myriad of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exceptional series finds extensive applications in diverse sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.
Distinctive Features
Its simplistic architecture allows for swift disassembly, ensuring user convenience.With regular maintenance schedules, our ball valves are engineered for effortless upkeep thanks to a non-tight fit design that minimizes service time.
Cutting-edge sealing technology assures unparalleled safety and security.The multi-layered sealing of both the stem and body delivers robust dual protection through the integration of O-ring and graphite or PTFE components.
This advanced design complies seamlessly with TA-Luft/Shell SPE 77/312 standards, assuring reliability.
Enduring Longevity, Enhanced Cost-EffectivenessFor metal-sealed ball valves, sophisticated processing techniques such as spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures hardness levels ranging from HRC58-73 and binding strengths of 80-40MPa. Moreover, they are capable of enduring over 100,000 on-off cycles with a leakage class of ANSI VI.
Convenience Through Modular DesignThe innovative modular design of the inner sealing facilitates the interchangeability of soft and metal seats for enhanced assurance.
Versatile Connection Types for Ease of UseOur diverse connection options, including flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, align with international standards, providing seamless and flexible usage.
Extensive Application Experience Ensures ReliabilitySNT Valves are extensively utilized across industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. We boast a sterling market reputation by providing well-founded solutions tailored to service conditions.
Structural Features
Our innovative packing combination is engineered to meet stringent regulatory demands by efficiently accommodating transmission requirements of 100 ppm. Simultaneously, it ingeniously reduces friction by an impressive 20% at the stem, ensuring smoother operation and enhanced durability.
1. The anti-blow out design is a crucial safeguard that effectively prevents the stem from being ejected, thereby averting potential damage and ensuring operational safety.
2. The seat ring's advanced structure, featuring a wave spring and dual-scraper, is adept at maintaining the pristine condition of the ball surface, while simultaneously ensuring an uncompromising seal for optimal performance.
3. Our sophisticated dual-sealing system is adept at ensuring superior leakage prevention, strategically designing the flow to avoid contact with the spring, thus maintaining an impeccable leakage class.
4. Experience unmatched reliability with the soft seat's sealing performance, which offers unparalleled stability and consistency for all your operational needs.
5. The innovative draining and sweeping design is meticulously crafted to avert any valve jamming incidents by effectively cleaning and maintaining the valve's pristine condition.
6. Our products adhere to API 607 standards, incorporating robust fire-proof and anti-static functionalities, providing you with peace of mind through enhanced safety features.
