Our ball and seat are fortified with an exceptional hard coating of chrome carbide or tungsten carbide, ensuring superior resistance to erosion and abrasion. This robust coating is a testament to the durability and longevity of our product, delivering sustained performance even in the most challenging conditions.
At SNT Machinery (Qingdao) Co., Ltd., we employ an advanced HVOF coating system. Our proprietary mate-lapping technique assures 100% sealing, combined with live loading to eliminate emissions entirely. Ingeniously crafted, the ball remains in constant contact with the seat, effortlessly sweeping away any contaminants. This innovative self-cleaning feature is a game changer, preventing damage and interference from foreign particles, making this valve an ideal choice for slurry and abrasive services.
These exceptional ball valves boast the following features:
The simple structure allows for quick disassembly, facilitating swift and efficient maintenance.
Thanks to regular maintenance practices, our ball valves are designed for easy upkeep, featuring a non-tight fit design that significantly reduces servicing time.
Our valves guarantee unmatched security with advanced sealing technology.
The innovative multi-layer combined sealing between the stem and body provides a robust double seal through the strategic combination of an O-ring with either graphite or PTFE.
This exemplary design meets the stringent standards of TA-Luft/Shell SPE 77/312.
A long service life ensures exceptional cost-effectiveness.
For metal-sealed ball valves, we employ cutting-edge processes for the ball and seat ring such as spray welding, spraying, and fusion welding. These techniques ensure a hardness level of HRC58-73 and a binding force of 80-40MPa. Remarkably, our valves can perform over 100,000 cycles with a leakage class rating of ANSI VI.
Convenience is enhanced through modular design.
The modular inner sealing design allows for the interchangeability of soft and metal seats, ensuring adaptability and efficiency in various applications.
Diverse connection types ensure user comfort and flexibility.
Our connection options include widely recognized international standards such as flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, guaranteeing convenient and adaptable usage.
