Product Description

 

Introducing our premier series of Zero-Leakage ball valves, expertly crafted for an array of demanding service applications. These valves are engineered to perform exceptionally under conditions of elevated temperature and pressure, ensuring unparalleled reliability and performance.
Our ball and seat components boast a hard coating of either chrome carbide or tungsten carbide, which endows them with exceptional resistance to erosion and abrasion. This superior protection ensures durability and longevity in the most challenging environments.
At SNT Machinery, we utilize a cutting-edge HVOF coating system, renowned for its precision and effectiveness. Our valves are mate-lapped using a proprietary technique that guarantees 100% sealing integrity. Live loading further assures zero emissions, while the innovative ball design maintains constant contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism safeguards against interference and damage from debris, rendering our valves ideal for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered in accordance with a wide array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. Our versatile product line is extensively utilized across numerous sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring robust performance in every application.

These valves boast the following distinctive features,
The straightforward design facilitates rapid disassembly, streamlining operational procedures.
Owing to the routine maintenance of our entire valve lineup, SNT ball valves are designed for easy upkeep, featuring a non-tight fit which significantly reduces servicing time, enhancing user convenience.

State-of-the-art sealing technology ensures unparalleled safety and security.
A sophisticated multi-layer sealing system, incorporating both O-rings and graphite or PTFE, delivers dual sealing for the stem and body, offering exceptional reliability.
This advanced sealing design complies with the rigorous TA-Luft and Shell SPE 77/312 standards, assuring high performance.

Extended service life maximizes cost-efficiency.
In our metal sealed ball valves, cutting-edge processing techniques such as spray welding and fusion welding are employed for the ball and seat ring. This ensures remarkable hardness levels of HRC58-73 and a binding force of 80-40MPa, allowing for over 100,000 on-off cycles while maintaining an ANSI VI leakage class.

The modular design enhances usability.
Our valves feature an innovative modular design that allows for easy interchangeability between soft and metal seats, ensuring adaptability and heightened performance.

Versatile connection types ensure ease of use.
Connection options include flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, all of which are internationally standardized, providing users with seamless and effortless integration.

Extensive application experience guarantees reliability.
SNT Valves, renowned for their extensive application in fields such as petroleum, chemical engineering, light industry, pharmaceuticals, paper-making, metallurgy, and power generation, have earned a stellar reputation.
