Product Description

Introducing our exceptional series of Zero-Leakage ball valves, expertly engineered to excel in a diverse range of demanding service applications characterized by elevated temperatures and/or pressures. Experience unparalleled reliability with our state-of-the-art valve solutions.
Our ball and seat components boast a superior hard coating of either chrome carbide or tungsten carbide, renowned for their outstanding resistance to erosion and abrasion. Choose our valves for durability and consistent performance in challenging environments.
At SNT Machinery, we embrace cutting-edge technology with our HVOF coating system. Our proprietary mate-lapping technique guarantees an impeccable 100% seal. Live loading technology ensures zero emissions. Ingeniously designed, the ball maintains constant contact with the seat, effectively wiping contaminants away. This innovative self-cleaning mechanism safeguards against interference and damage, making our valve an ideal choice for slurry and abrasive services.

 

Our Advantages

SNT Ball Valves are engineered to the pinnacle of precision, aligning with a plethora of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. Our versatile product line serves a diverse array of industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Discover the Remarkable Features:
Ingenious design with a streamlined structure allowing rapid disassembly.
Thanks to regular maintenance, our ball valves provide user-friendly serviceability with a non-tight fit design, significantly reducing maintenance time.

Innovative sealing ensures maximum security.
The multi-layered sealing system for both stem and body employs a strategic combination of O-rings and either graphite or PTFE, delivering robust double-sealing capabilities.
This exceptional design is compliant with TA-Luft/Shell SPE 77/312 standards.

Extended longevity translates to unparalleled cost efficiency.
For our metal-sealed ball valves, we utilize cutting-edge processing techniques such as spray welding, spraying, and fusion welding to achieve a surface hardness of HRC58-73 and a binding force between 80-40MPa. This ensures over 100,000 on-off cycles and a leakage class of ANSI VI.
 

Modular engineering provides ultimate flexibility.
The modular design of the internal sealing allows for the interchangeability of soft and metal seats, ensuring adaptability and efficiency.

Diverse connection options enhance user convenience.
Connection choices include the universally recognized flanged type (RF, FF, FM, G, RJ), screw-thread type, and BW type, offering seamless usability.

Extensive experience in application assures reliability.
With a strong presence across industries including petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, SNT Valve has earned a stellar reputation for delivering sensible solutions tailored to specific service conditions.
