Our ball valves are meticulously crafted with a hard coat of chrome carbide or tungsten carbide on the ball and seat. This advanced coating provides exceptional erosion and abrasion resistance, ensuring durability and longevity even under the harshest conditions.
At SNT Machinery, we employ the cutting-edge HVOF coating system. Each valve component is mate-lapped using our proprietary technique, guaranteeing a 100% sealing capability. The innovative live loading feature ensures zero emissions, while the unique construction of the valve ensures the ball never departs from the seat. This design inherently wipes away contaminants, offering a self-cleaning mechanism that prevents any interference or damage from external particles. This remarkable feature makes our valve an ideal choice for slurry and abrasive service applications, where reliability and performance are paramount.
Key Features and Benefits
The straightforward design facilitates quick disassembly, ensuring effortless operational efficiency.
Thanks to the routine maintenance of all our valves, SNT ball valves are designed for effortless upkeep with a non-tight fit design, significantly reducing servicing time.
Enhanced Sealing for Utmost Security
The multi-layer combined sealing of the stem and body provides a dual sealing solution through the integration of O-ring and either graphite or PTFE, ensuring robust protection.
This innovative sealing design is compliant with TA-Luft/Shell SPE 77/312 standards, ensuring high reliability.
Extended Service Life for Superior Cost-Effectiveness
For our metal-sealed ball valves, we utilize cutting-edge techniques such as spray welding, spraying, and fusion welding on the ball and seat ring to assure a hardness of HRC58-73 and a binding force of 80-40MPa. These features ensure the valves can operate beyond 100,000 on-off cycles while maintaining an ANSI VI leakage class.
Modular Design for Enhanced Convenience
The modular design of inner sealing allows for the interchangeability of soft and metal seats, providing adaptable solutions for varying needs.
Versatile Connection Types for User-Friendly Experience
Our connection types include flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all of which are internationally standardized to offer simple and convenient usage.
Rich Application Experience Ensures Reliability
SNT Valves have been extensively implemented across various sectors such as petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations. We have garnered an excellent market reputation, providing logical solutions tailored to specific service conditions.
Our innovative packing combination is engineered to achieve superior smission efficiency with an impressive 100 ppm, while simultaneously minimizing friction to the stem by a remarkable 20%. This ensures optimal performance and longevity.
2. The advanced seat ring architecture, incorporating wave spring and dual-scraper technology, meticulously cleans the ball surface, maintaining impeccable sealing integrity at all times.
3. Our dual-sealing system is expertly engineered to uphold the highest leakage class standards by ensuring the flow remains untouched by the spring, delivering reliable leak prevention.
4. Experience enhanced stability and reliability with the soft seat's outstanding sealing performance, offering peace of mind in every use.
5. The innovative design for draining and sweeping is tailored to prevent valve jamming, ensuring seamless operation through effective cleaning mechanisms.
