Product Description

Discover the unmatched excellence of our Zero-Leakage ball valves, masterfully engineered for a multitude of service applications requiring resilience against high temperatures and/or high pressures. Embrace the reliability that only SNT Machinery (Qingdao) Co., Ltd. can provide.
Our valves boast a cutting-edge design with their ball and seat meticulously hard-coated using premium chrome carbide or tungsten carbide materials. This innovative coating ensures exceptional resistance to erosion and abrasion, maintaining peak performance over extended use.
At SNT, our valves are perfected using the advanced HVOF coating system, guaranteeing a flawless 100% seal through our exclusive mate-lapping technique. The live loading feature promises absolute zero emissions, while the ball's constant contact with the seat effectively wipes away contaminants. This self-cleaning mechanism protects the valve from interference and damage, rendering it ideal for both slurry and abrasive service applications.

 

Our Advantages

SNT Ball Valves are meticulously engineered to conform with a diverse array of international standards, including ASME B 16.34-2009, ASME B16.10-2000, and API 589-2009, among others. This exceptional series is extensively employed across various sectors such as petroleum, the chemical industry, light industry, pharmacy, paper-making, metallurgy, and power stations.

These valves boast the following impressive characteristics:
Their straightforward design allows for quick disassembly, greatly simplifying maintenance processes.
Thanks to the periodic maintenance of all valves, our ball valves are engineered for effortless upkeep. The non-tight fit design significantly reduces servicing time, providing unparalleled ease in maintenance.

Cutting-edge sealing technology ensures unmatched security and reliability.
The multi-layered sealing system, comprising both the stem and body, delivers a robust double sealing solution through the combination of O-ring and graphite or PTFE materials.
This innovative design complies meticulously with TA-Luft/Shell SPE 77/312 standards.

Durability leads to exceptional cost-effectiveness over the lifespan of the valves.
Our metal-sealed ball valves undergo advanced processing techniques, including spray welding and fusion welding of the ball and seat ring. This ensures a hardness of HRC58-73 and a binding force of 80-40MPa. Additionally, they can withstand over 100,000 on-off cycles with a leakage class of ANSI VI.
 

The modular design aspect provides remarkable convenience and flexibility.
The modular design of the inner sealing allows for seamless interchangeability between soft and metal seats, enhancing adaptability and ensuring optimal performance.

Diverse connection types ensure ease and comfort in application.
Our versatile connection options include flanged types (RF, FF, FM, G, RJ), screw-thread types, and BW types. These universally recognized standards offer unmatched user convenience.

Extensive application experience assures reliability and trust.
SNT Valve's extensive application across industries such as petroleum, chemical, light industry, pharmacy, paper-making, metallurgy, and power stations has solidified our reputation. We consistently provide sensible solutions tailored to specific service conditions, earning us a favorable reputation in the market.

 

Structural Features

Our innovative special packing combination is engineered to not only meet stringent emission requirements of 100 ppm but also to significantly reduce friction by 20%, ensuring optimal efficiency and durability of the stem.

1. Ingeniously designed with an anti-blowout feature, our valves efficiently prevent the stem from being ejected, thus safeguarding against potential damage and enhancing reliability.

2. The advanced structure of the seat ring, featuring a wave spring and dual-scraper, excels in cleaning the ball surface, thereby maintaining impeccable sealing and extending the longevity of the valve.

3. Our dual-sealing mechanism is meticulously crafted to assure superior leakage prevention, ensuring the flow does not contact the spring, thus maintaining the highest standards of leakage class.

4. Experience unprecedented stability and reliability with our soft seat sealing, designed to perform consistently even under demanding conditions.

5. The thoughtfully designed draining and sweeping functionality effectively prevents jamming by thoroughly cleaning the valve, ensuring seamless operation.

6. Adhering to the rigorous API 607 standards, our valves are equipped with robust fire-proof and anti-static features, providing enhanced safety and peace of mind.
