Product Description

^{Introducing the High Performance Soft Seated Ball Valve series, a remarkable innovation from SNT Machinery (Qingdao) Co., Ltd. These valves are meticulously crafted to deliver unparalleled Zero-Leakage performance, making them the ideal choice for an array of high-temperature and high-pressure service applications.
Engineered with unmatched precision, the ball and seat of these superior valves are fortified with advanced coatings of chrome carbide or tungsten carbide. This exceptional strengthening process provides remarkable resistance to erosion and abrasion, significantly enhancing the lifespan and reliability of the valves.
Our SNT High Performance Soft Seated Ball Valves utilize a cutting-edge HVOF coating system. Every valve undergoes meticulous mate-lapping with proprietary techniques, ensuring flawless 100% sealing. The innovative live loading feature guarantees zero emissions, with the ball consistently engaging the seat to effectively remove contaminants. This state-of-the-art self-cleaning mechanism is adept at preventing interference and damage from particles, qualifying these valves as an exceptional choice for slurry and abrasive service applications.}

Structure Features

 

<sup>Our specialized packing combination not only meets the stringent emission requirements of 100 ppm but also impressively reduces the friction on the stem by 20%, contributing to smoother and more efficient operations.

Ingeniously crafted with an anti-blowout design, our product ensures that the stem remains securely in place, effectively preventing any damage that could be caused by blowouts.

The innovative seat ring structure, featuring a wave spring and dual-scraper, efficiently cleans the ball surface while maintaining impeccable sealing performance.

Our dual-sealing mechanism is engineered to perfection, ensuring top-notch leakage prevention by keeping the flow away from the spring, thereby guaranteeing superior leakage class.</sup>

The soft seat sealing performance is exceptionally stable and reliable, delivering consistent results and peace of mind during operations.

Our advanced draining and sweeping design skillfully prevents the valve from becoming jammed, maintaining optimal cleanliness and functionality.

Meticulously designed to comply with API 607 standards, our valves boast fire-proof and anti-static features, ensuring safety and reliability in demanding environments.

Our Advantages

SNT Ball Valves are crafted with precision to adhere to a comprehensive array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This highly adaptable series sees widespread use across a multitude of sectors, including petroleum, chemical processing, light manufacturing, pharmaceuticals, paper production, metallurgy, and power generation facilities.

Their Remarkable Features Include:
Effortless disassembly thanks to an elegantly streamlined design.
Engineered with a focus on easy maintenance, our ball valves boast a non-tight fit design that allows for rapid servicing, significantly reducing downtime during scheduled maintenance procedures.

Innovative sealing technology ensuring maximum security.
The multi-layer sealing system incorporating both O-ring and graphite or PTFE provides dual-level protection, delivering superior sealing efficacy.
This pioneering design rigorously meets the stringent TA-Luft/Shell SPE 77/312 standards.

Prolonged Service Life for Exceptional Cost-Efficiency
