Product Description

 

Introducing our top-tier series of Zero-Leakage ball valves, expertly designed to excel in a spectrum of critical service applications. These innovative ball valves are engineered to withstand extreme high-temperature and high-pressure conditions, ensuring seamless and reliable performance.
The ball and seat of these valves are meticulously hard-coated with either premium chrome carbide or tungsten carbide, offering remarkable resistance to erosion and abrasion. This double-layer of protection ensures longevity and durability in demanding environments.
At SNT Machinery (Qingdao) Co., Ltd., we employ the advanced HVOF coating system to achieve superior surface finishes. Our proprietary mate-lapping process guarantees impeccable 100% sealing, while live loading ensures zero emissions for utmost safety. Ingeniously designed, the ball maintains constant contact with the seat, effectively wiping away any contaminants. This self-cleaning mechanism prevents interference and damage from debris, making the valve ideally suited for slurry and abrasive service applications.

 

 

 

 

 

Our Advantages

 

SNT Ball Valves are meticulously engineered to surpass a variety of international benchmarks, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This versatile product line finds extensive applications across the petrol, chemical industries, light industries, pharmaceuticals, paper-making, metallurgy, and power stations, demonstrating unparalleled reliability and efficiency.

Our valves boast the following distinctive characteristics:
Ingeniously simple structure ensures rapid disassembly.
Thanks to regular maintenance protocols, our ball valves are designed with a non-tight fit feature that simplifies servicing, significantly reducing maintenance time and enhancing efficiency.

State-of-the-art sealing technology ensures unparalleled security.
The combination of a multi-layer sealing system, incorporating O-rings and either graphite or PTFE, provides a robust dual-sealing solution between stem and body, enhancing secure operations.
This innovative design complies with stringent TA-Luft/Shell SPE 77/312 standards.

Durable design for cost-effective, long-term operation.
For our metal-sealed ball valves, advanced processes like spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures hardness levels from HRC58 to HRC73, binding forces from 80-40MPa, and more than 100,000 on-off cycles with leakage class conforming to ANSI VI standards.

Modular design enhances convenience and adaptability.
The innovative modular design of the inner sealing system allows for the interchangeability of soft and metal seats, ensuring versatile adaptability to your needs.

Diverse connection options provide effortless adaptability.
Our connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, are globally standardized, offering exceptional ease of use and adaptability to various systems.

Extensive practical experience ensures unwavering reliability.
SNT Valves have earned a stellar reputation across a broad spectrum of industries, such as petroleum, chemical, light industries, pharmaceuticals, paper-making, metallurgy, and power stations. Our solutions are tailored to meet specific service conditions, ensuring reliability and trustworthiness in every application.

Structural Features

 

Innovative packing combinations are designed to meet stringent emission requirements of 100 ppm, while simultaneously reducing friction by an impressive 20%, enhancing the longevity and efficiency of the stem.

1. The anti-blowout stem design is a critical safety feature, effectively preventing any accidental ejection of the stem, thereby safeguarding against potential damage.

2. Featuring a seat ring structure with wave springs and dual-scraper technology, this design effectively cleans the ball surface, maintaining optimal sealing integrity at all times.

3. The dual-sealing mechanism ensures superior leakage class standards, cleverly engineered so that the flow never contacts the spring, preserving its efficacy.

4. The soft seat's sealing performance is remarkably stable and reliable, providing consistent and dependable sealing capability.

5. Our innovative draining and sweeping design actively prevents blockages, ensuring the valve remains free from jams and operates smoothly.

6. Rigorously compliant with API 607 standards, this valve offers enhanced fire-proof and anti-static capabilities, ensuring safety and reliability in all conditions.
