Product Description

^{Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery(Qingdao) Co., Ltd. Expertly crafted to perfection, these valves deliver unparalleled Zero-Leakage performance, making them ideal for a wide range of rigorous high-temperature and high-pressure service applications.
Crafted with impeccable precision, the ball and seat of these valves boast advanced hard coatings of chrome carbide or tungsten carbide. This superior reinforcement provides extraordinary resistance to erosion and abrasion, thereby significantly enhancing the valve's durability and reliability over time.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system, ensuring each valve is meticulously mate-lapped using exclusive proprietary techniques for a perfect 100% seal. The innovative live loading functionality guarantees zero emissions, with the ball maintaining continuous contact with the seat to effectively sweep away contaminants. This state-of-the-art self-cleaning mechanism prevents particle interference and damage, rendering these valves the ultimate solution for slurry and abrasive service applications.}

Structure Features

 

<sup>Our unique special packing combination adeptly meets the stringent emission requirements of 100 ppm, while expertly reducing stem friction by an impressive 20%.

Ingeniously designed with an anti-blowout feature, this valve ensures that the stem remains securely in place, preventing any potential damage due to blowout.

Featuring a sophisticated seat ring structure with a wave spring and dual-scraper, this design effectively cleans the ball surface, ensuring a pristine seal is maintained.

The innovative dual-sealing mechanism guarantees top-tier leak class performance by ingeniously preventing the flow from contacting the spring.</sup>

The sealing performance of our soft seat is exceptionally stable and reliable, providing consistent sealing integrity over time.

Designed with a highly efficient draining and sweeping feature, this valve effectively prevents jamming by thoroughly cleaning.

Engineered to comply with API 607 standards, this valve offers robust fire-proof and anti-static functionalities, ensuring safety and reliability.

Our Advantages

SNT Ball Valves are crafted with precision to meet a wide array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series enjoys widespread utilization in diverse sectors such as petroleum, chemical manufacturing, light industries, pharmaceuticals, paper production, metallurgy, and power generation facilities.

Exceptional Features That Set Us Apart:
A sleek and intuitive design ensures effortless disassembly.
Crafted for efficiency and ease, our ball valves boast a non-tight fit design, simplifying maintenance procedures and significantly reducing downtime during regular service intervals.

Advanced sealing technology ensures utmost safety and security.
The sophisticated multi-layer sealing of both stem and body provides dual-layer protection via a synergistic use of O-ring alongside graphite or PTFE, delivering unmatched sealing integrity.
This state-of-the-art design conforms to the stringent TA-Luft/Shell SPE 77/312 standards.

Prolonged Operational Life for Cost-Effective Performance
Our metal seated ball valves benefit from cutting-edge processing methods, including spray welding, spraying, and fusion welding. This results in a hardness scale of HRC58-73 and a binding force rated at 80-40MPa, with an exceptional cycle life surpassing 100,000 operations and a leak class of ANSI VI.

Innovative Modular Design for Added Flexibility
The versatile modular inner sealing framework enables seamless interchangeability between soft and metal seats, guaranteeing adaptability and dependable performance.
