Introducing the High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. These expertly engineered valves are designed to deliver exceptional Zero-Leakage performance, perfectly suited for diverse high-temperature and high-pressure service applications. With precision craftsmanship, they stand out in reliability and durability.
Crafted with unparalleled precision, the ball and seat of these valves are fortified with advanced hard chrome carbide or tungsten carbide coatings. This superior reinforcement guarantees outstanding resistance to erosion and abrasion, significantly enhancing valve longevity and operational reliability.
Our SNT High Performance Soft Seated Ball Valves boast a cutting-edge HVOF coating system. Each valve undergoes meticulous mate-lapping with proprietary techniques to ensure a flawless 100% sealing. The innovative live loading feature promises zero emissions, while maintaining constant contact between the ball and seat to effectively wipe away contaminants. This pioneering self-cleaning mechanism prevents any interference or damage from particles, making these valves the ideal choice for slurry and abrasive service applications.
Structure Features
Our specialized packing combination is expertly engineered to fulfill the stringent emission requirement of 100 ppm. Simultaneously, it achieves a remarkable 20% reduction in friction, enhancing the efficiency and longevity of the stem.
Ingeniously designed with an anti-blowout feature, our system effectively prevents the stem from blowing out, thereby averting potential damage and ensuring reliable operation.
The innovative seat ring structure, incorporating a wave spring and dual-scraper, is crafted to meticulously clean the ball surface, maintaining an impeccable seal for optimal performance.
Dual-sealing technology ensures superior leakage class by ingeniously preventing the flow from contacting the spring, thus reinforcing the valve's effectiveness and reliability.
The sealing performance of our soft seat is exceptionally stable and reliable, offering superior protection and durability under varying operational conditions.
Our design includes a robust draining and sweeping feature that expertly prevents valve jamming by thorough cleaning, ensuring seamless operation.
