Product Description

Discover our exceptional series of Zero-Leakage ball valves, meticulously designed to excel in diverse applications that demand resilience against high temperature and pressure. Experience unparalleled performance across your industrial operations with our state-of-the-art ball valves.
Our valves feature a robust ball and seat, expertly hard coated with premium materials like chrome carbide or tungsten carbide. This superior surface treatment ensures remarkable resistance to erosion and abrasion, extending the lifespan and reliability of our products in demanding industrial environments.
At SNT, we pride ourselves on utilizing advanced HVOF coating systems. Our proprietary mate-lapping technique guarantees an impeccable 100% seal, while live loading mechanisms ensure zero emissions. The innovative design allows the ball to continuously wipe away contaminants, maintaining a pristine surface. This self-cleaning feature effectively shields the valve from interference and damage, making it ideal for slurry and abrasive service conditions.

 

Our Advantages

SNT Ball Valves are meticulously crafted to align with an array of prestigious international standards including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This versatile series finds its application across diverse sectors such as petroleum, the chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power generation. Its adaptability and compliance ensure a broad spectrum of industrial utilization.

Distinctive Character Traits:
Ingenious simplicity in design facilitates rapid disassembly.
Through meticulous periodic maintenance, our ball valves are engineered for effortless upkeep. The non-tight fit design significantly reduces servicing time, enhancing operational efficiency.

Pioneering sealing solutions assure absolute safety.
The multi-layer combined sealing technology of the stem and body ensures a robust dual sealing effect, utilizing a strategic combination of O-ring and either graphite or PTFE.
This sophisticated sealing architecture complies with esteemed TA-Luft/Shell SPE 77/312 standards.

Extended longevity translates to economic efficiency.
In metal-sealed ball valves, we employ advanced techniques such as spray welding, spraying, and fusion welding on the ball and seat ring. This ensures a hardness rating of HRC58-73 and a binding force of 80-40MPa. Impressively, these valves can endure over 100,000 operational cycles with a leakage class of ANSI VI.
 

Modularity in design enhances user convenience.
The modular design of internal sealing components allows for the interchangeability between soft and metal seats, rendering it highly adaptable to different requirements.

Versatile connection options for seamless integration.
Our connection types, which include flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, adhere to international standards, ensuring ease of use and global compatibility.

Vast application experience ensures dependable performance.
SNT Valves are extensively utilized across industries such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations. Our sterling market reputation underscores our commitment to delivering optimal solutions tailored to specific service conditions.

 

Structural Features

Our innovative packing combination superbly achieves the stringent transmission requirement of 100 ppm. At the same time, it ingeniously reduces friction by 20% to the stem, ensuring smooth and efficient operation.

1. An expertly crafted anti-blowout design is employed to safeguard against stem blowouts, thereby preventing potential damage and ensuring utmost safety.

2. The sophisticated structure of the wave spring seat ring paired with dual-scraper technology effectively cleans the ball surface, maintaining impeccable sealing integrity.

3. Our advanced dual-sealing feature guarantees an impeccable leakage class by ensuring that the flow never comes into contact with the spring, enhancing the reliability of the seal.

4. The soft seat sealing is engineered for superior performance, offering stability and reliability that is unmatched.

5. Ingenious draining and sweeping design preemptively prevents valve jamming, keeping it pristine and functional through thorough cleaning.

6. Fully compliant with API 607 standards, our designs boast fire-proof and anti-static functions, ensuring top-tier safety and durability.
