These meticulously engineered valves deliver unparalleled Zero-Leakage performance, making them ideal for a wide range of demanding high-temperature and high-pressure service applications. Designed with precision, our valves stand out in the industry for their exceptional durability and reliability.
Crafted with unmatched precision, the ball and seat of these valves are reinforced with advanced hard coatings of either chrome carbide or tungsten carbide. This superior fortification provides exceptional resistance against both erosion and abrasion, significantly enhancing the longevity and reliability of the valves. Trust in the robust design that stands the test of time, ensuring smooth operation under the toughest conditions.
Our SNT High Performance Soft Seated Ball Valves feature a state-of-the-art HVOF coating system. Each valve undergoes meticulous mate-lapping using proprietary techniques to guarantee flawless 100% sealing. The innovative live loading feature ensures zero emissions, maintaining optimal performance. The ball remains in constant contact with the seat, effectively wiping away contaminants. This cutting-edge self-cleaning mechanism prevents interference and damage from particles, making these valves the perfect choice for slurry and abrasive service applications. Experience the pinnacle of reliability and efficiency with our advanced valve technology.
This unique special packing combination is meticulously crafted to meet stringent emission requirements of 100 ppm, while ingeniously minimizing friction by an impressive 20% against the stem. Experience superior performance with reduced wear and enhanced durability.
Our innovative anti-blowout design ensures that the stem remains securely in place, effectively preventing any incidents of blowouts that could result in damage. This superior safety feature is engineered for reliability and peace of mind.
The cutting-edge structure of our seat ring, featuring a wave spring and dual-scraper, is designed to meticulously clean the ball surface, maintaining pristine conditions and ensuring impeccable sealing at all times.
The dual-sealing mechanism is a testament to engineering excellence, guaranteeing the highest leak-proof standards by ingeniously preventing the flow from contacting the spring, thus ensuring uncompromising reliability.
Our soft seat sealing performance is renowned for its enhanced stability and reliability, offering you long-lasting assurance and peace of mind with every use.
The innovative design of our draining and sweeping mechanism effectively prevents the valve from becoming jammed, ensuring seamless operation through thorough cleaning.
Meticulously crafted in compliance with API 607 standards, our product boasts fire-proof and anti-static functionalities, setting a benchmark for safety and performance.
SNT Ball Valves are precision-engineered, meticulously crafted to adhere to a broad spectrum of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This multifaceted series serves a wide array of industries, encompassing petroleum, chemical industry, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, ensuring unparalleled versatility.
