Introducing the exceptional High Performance Soft Seated Ball Valve series by SNT Machinery (Qingdao) Co., Ltd. Impeccably designed, these state-of-the-art valves deliver unrivaled Zero-Leakage performance, tailor-made for the most demanding high-temperature and high-pressure service applications. Experience the pinnacle of engineering excellence in every operation.
Crafted with unparalleled precision, the ball and seat of these extraordinary valves are fortified with cutting-edge hard coatings of chrome carbide or tungsten carbide. This remarkable enhancement ensures outstanding resistance to erosion and abrasion, significantly boosting the longevity and reliability of the valves. Trust in the superior durability provided by this advanced engineering.
Our SNT High Performance Soft Seated Ball Valves boast an advanced HVOF coating system, incorporating cutting-edge technology. Each valve is meticulously mate-lapped using proprietary techniques to deliver flawless 100% sealing. The innovative live loading feature guarantees zero emissions, maintaining constant contact between the ball and seat to effectively remove contaminants. This sophisticated self-cleaning mechanism prevents interference and damage from particles, establishing these valves as the ideal choice for demanding slurry and abrasive service applications.
Our unique special packing combination is expertly engineered to meet stringent emission requirements of 100 ppm while simultaneously reducing friction by an impressive 20% at the stem, ensuring optimal performance and longevity.
The advanced anti-blowout design effectively prevents the stem from being expelled, thereby safeguarding against potential damage to the casing-a testament to our commitment to safety and reliability.
The innovative seat ring structure, featuring a wave spring and dual-scraper system, is designed to meticulously clean the ball surface, ensuring impeccable sealing integrity and long-lasting performance.
Our dual-sealing technology is engineered to ensure leak-proof performance by cleverly preventing fluid from contacting the spring, thus upholding the highest leakage class standards.
The sealing performance of our soft seat is crafted to be exceptionally stable and reliable, providing consistent and dependable operation in diverse applications.
The meticulously designed draining and sweeping function effectively prevents the valve from becoming jammed, ensuring smooth operation and enhanced cleanliness.
This product is fully compliant with API 607 standards, boasting remarkable fire-proof and anti-static capabilities, underscoring its superior safety and durability features.
SNT Ball Valves are masterfully crafted to adhere to a comprehensive array of international standards, including ASME B16.34-2009, ASME B16.10-2000, and API 589-2009. This adaptable series is indispensable across a multitude of industries, such as petroleum, chemical, light industry, pharmaceuticals, paper-making, metallurgy, and power stations.
Their Remarkable Features Include:
Elegant, streamlined design for effortless disassembly.
Intelligently conceived with maintenance simplicity at its core, our ball valves boast a non-tight fit design, allowing for swift and efficient servicing. This strategic design reduces operational downtime during essential maintenance routines.
Pioneering sealing technology ensuring ultimate security.
