Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Experience engineering excellence with meticulously designed valves that provide unrivaled Zero-Leakage performance across a spectrum of demanding high-temperature and high-pressure service environments.
Engineered with precision beyond compare, these valves boast a ball and seat reinforced with advanced hard coatings, including chrome carbide and tungsten carbide. This superior protection offers extraordinary resistance to erosion and abrasion, ensuring enhanced durability and unwavering reliability.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system. Each valve is subjected to meticulous mate-lapping with proprietary techniques to ensure an impeccable 100% seal. Featuring an innovative live loading design, these valves guarantee zero emissions, maintaining constant ball-to-seat contact to eliminate contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the ultimate solution for slurry and abrasive service applications.
Our special packing combination is engineered to meet rigorous emission requirements of 100 ppm, while simultaneously reducing stem friction by an impressive 20%, ensuring superior performance and longevity.
The anti-blow out design is a safety innovation that prevents the stem from being expelled, thereby safeguarding the valve from potential damage and ensuring reliable operation.
Ingeniously crafted, the seat ring structure, featuring a wave spring and dual-scraper, efficiently cleans the ball surface and maintains exceptional sealing integrity.
Our dual-sealing mechanism guarantees superior leakage prevention by ensuring that the flow never comes into contact with the spring, thereby maintaining the highest leak-tightness standards.
The enhanced sealing performance of our soft seat design is not only more stable but also exceptionally reliable, providing peace of mind in demanding applications.
The innovative design incorporating draining and sweeping functions effectively prevents the valve from jamming, ensuring optimal cleanliness and uninterrupted operation.
Engineered to comply with API 607 standards, our valves feature robust fire-proof and anti-static capabilities, offering unparalleled safety and reliability.
At SNT Machinery (Qingdao) Co., Ltd., our Advanced Soft Seated Trunnion Ball Valves are the epitome of engineering excellence, meticulously crafted to align with a wide array of international standards, such as ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This versatile and robust series of ball valves finds widespread applications across diverse industries, including petroleum, chemicals, light industry, pharmaceuticals, paper-making, metallurgy, and power stations, making them indispensable in the modern industrial landscape.
