Product Description

 

Introducing our state-of-the-art series of Zero-Leakage Ball Valves, meticulously crafted for an array of challenging service applications that demand high-temperature and/or high-pressure conditions. These exceptional valves are engineered to deliver outstanding performance and reliability.
The robust ball and seat are fortified with an advanced hard coating of chrome carbide or tungsten carbide, offering unparalleled resistance to erosion and abrasion. This superior durability ensures the longevity and dependability of our valves.
At SNT Machinery (Qingdao) Co., Ltd., we employ a cutting-edge HVOF coating system, perfectly complemented by our proprietary mate-lapping technique. This guarantees 100% sealing efficiency. Our innovative design incorporates live loading, ensuring zero emissions. The ball remains in constant contact with the seat, adeptly sweeping away contaminants, thereby maintaining a pristine operational environment. This self-cleaning mechanism safeguards the valve against interference and damage, making it exceptionally suitable for slurry and abrasive services.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered to adhere to a plethora of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009. This exemplary series finds its applications across diverse sectors such as petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.

Distinguished Features:
Ingenious Design Ensures Effortless Disassembly
Through routine maintenance protocols, our ball valves are crafted for easy maintenance, thanks to their non-tight fit architecture, minimizing servicing time and effort.

State-of-the-Art Sealing for Absolute Safety
The sophisticated multi-layer combined sealing between the stem and body offers robust double sealing through the integration of O-ring, graphite, or PTFE, ensuring maximum security.
This cutting-edge design is compliant with TA-Luft/Shell SPE 77/312 standards.

Prolonged Service Life for Optimal Cost Efficiency
In our metal-sealed ball valves, advanced techniques such as spray welding, spraying, and fusion welding are employed for the ball and seat ring to achieve a hardness of HRC58-73 and a binding force of 80-40MPa. These valves are capable of over 100,000 on-off cycles while maintaining an ANSI VI leakage class.

Modular Structure for Ultimate Convenience
The modular inner sealing design facilitates seamless interchangeability between soft and metal seats.

Versatile Connection Options for User Comfort
Our connections come in international standards, including flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types, ensuring ease of use and installation.

Extensive Expertise Guarantees Unmatched Reliability
SNT Valves have earned extensive deployment in industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Known for our reputable standing in the market, we deliver optimal solutions tailored to service conditions.

Structural Features

 

Ingeniously crafted, the special packing combination not only fulfills the stringent emission standards of 100 ppm but also skillfully reduces friction on the stem by a substantial 20%, enhancing operational efficiency.

1. The advanced anti-blowout design ensures the stem remains securely in place, preventing any potential damage and enhancing safety.

2. The innovative seat ring structure, featuring a wave spring and dual-scraper, effectively cleans the ball surface and maintains an impeccable seal.

3. Our dual-sealing system guarantees the highest leakage class by cleverly preventing the flow from contacting the spring, ensuring superior performance.

4. Experience the reliability and stability of our soft seat, offering consistently outstanding sealing performance.

5. The thoughtfully designed draining and sweeping features ensure the valve remains free from jams, maintaining optimal cleanliness and performance.

6. Adhering to strict API 607 standards, this design incorporates fire-proof and anti-static functions to ensure maximum safety and compliance.
