The ball and seat within our valves are fortified with a robust hard coating of chrome carbide or tungsten carbide, renowned for their superior resistance to erosion and abrasion. This advanced treatment ensures durability and longevity under the most demanding conditions.
At SNT, we employ the cutting-edge HVOF coating system. With our proprietary mate-lapped technique, we guarantee 100% sealing integrity. The inclusion of live loading further assures zero emissions, maintaining environmental standards. Designed for optimal performance, the ball remains in constant contact with the seat, effortlessly wiping away contaminants. This self-cleaning mechanism protects against interference and potential damage from debris, making this valve the ideal choice for both slurry services and abrasive operations.
Distinctive Features and Characteristics:
Ingenious, Simple Structure Ensures Effortless Disassembly
With regular maintenance intervals, our ball valves are designed for user-friendly servicing. The non-tight fit design reduces maintenance time, offering unparalleled convenience.
Innovative Sealing for Enhanced Security
The multi-layer combined sealing system of the stem and body provides robust double sealing with a blend of O-ring and graphite or PTFE, ensuring reliability.
This expertly crafted design complies with TA-Luft and Shell SPE 77/312 standards.
Extended Service Life for Unmatched Cost-Effectiveness
For metal-sealed ball valves, advanced techniques like spray welding, spraying, and fusion welding are employed for the ball and seat ring. This ensures a hardness level of HRC58-73 and a binding force range of 80-40MPa, enabling over 100,000 on-off cycles with leakage class conforming to ANSI VI.
Modular Design Offers Supreme Flexibility
The innovative modular design of the inner sealing allows for interchangeable soft and metal seats, ensuring adaptability and seamless performance.
Diverse Connection Types for Optimal Ease of Use
Our valves offer various connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, all adhering to international standards, providing utmost convenience and ease of use.
Extensive Application Experience Guarantees Unshakable Reliability
