Product Description
Introducing our premium series of Efficient Control Valves: Ball Valves with Floating Design Features. These engineering marvels are designed to deliver impeccable performance across a range of demanding service applications. Whether you are dealing with high temperature or high pressure, our zero-leakage ball valves stand ready to meet your every need with unmatched precision and reliability.
Crafted with excellence, the ball and seat of our valves are fortified with a hard coating of either chrome carbide or tungsten carbide. This meticulous coating process imbues the valves with exceptional erosion and abrasion resistance, ensuring longevity and durability even under the harshest conditions.
At SNT Machinery (Qingdao) Co., Ltd., we employ an advanced HVOF coating system, coupled with a proprietary mate-lapping technique to guarantee 100% sealing efficiency. Our live loading feature further ensures absolute zero emissions, making our valves environmentally friendly. The innovative design keeps the ball constantly in contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism safeguards the valves from interference and damage, making them perfectly suited for slurry and abrasive services.
Our Advantages
SNT Ball Valves are meticulously crafted to align with a spectrum of prestigious international standards such as ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. These remarkable products find extensive application across diverse industries including petrol, chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations.
Distinctive Features of Our Valves Include:
The straightforward structure ensures rapid disassembly.With regular maintenance protocols in place, our ball valves are engineered for effortless upkeep thanks to a non-tight fit design that significantly reduces maintenance time.
Enhanced Sealing for Uncompromised SecurityThe multi-layered sealing system of the stem and body provides dual protection through a combination of O-ring and either graphite or PTFE, ensuring superior sealing.
This innovative design meets the rigorous standards of TA-Luft/Shell SPE 77/312, attesting to its quality.
Extended Lifespan for Maximum Cost EfficiencyFor our metal-sealed ball valves, advanced techniques like spray welding, spraying, and fusion welding are employed on the ball and seat ring. This ensures hardness levels of HRC58-73 and a robust binding force of 80-40MPa. Moreover, these valves can withstand over 100,000 cycles, maintaining an ANSI VI leakage class.
Convenient Modular DesignThe ingenious modular design of the inner sealing allows for the interchangeability of both soft and metal seats, ensuring versatility and reliability.
Versatile Connection Options for Enhanced UsabilityOur diverse connection options include internationally standardized types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW, providing users with unparalleled convenience.
Extensive Application Experience Ensures TrustworthinessSNT Valves have gained widespread acceptance in petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power station sectors. Our esteemed reputation in the market is built on delivering optimal solutions tailored to specific service conditions.
Structural Features
Our specially engineered packing combination is designed to meet stringent transmission requirements of 100 ppm, while ingeniously reducing the stem friction by a remarkable 20%.
1. The innovative anti-blowout design is crafted to securely prevent the stem from being ejected, thereby safeguarding against potential damage.
2. The seat ring structure, enhanced with a wave spring and dual-scraper technology, effectively cleans the ball surface and ensures impeccable sealing integrity.
3. Our dual-sealing mechanism is expertly designed to maintain the leakage class by ensuring that the flow never contacts the spring, providing superior leak prevention.
4. Experience enhanced stability and reliability with our soft seat's exceptional sealing performance, guaranteeing peace of mind in every operation.
5. The thoughtfully designed draining and sweeping features are meticulously crafted to prevent valve jamming by thoroughly cleaning the internal components.
6. Proudly complying with API 607 standards, our valves boast essential fire-proof and anti-static capabilities, ensuring maximum safety and reliability.
