ANSI 150-600 Butt Welding Metal Seated Ball Valves with Floating Design Features with Stainless Steel/ANSI B16.014 V/API 598 Leakage

 
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 Security
The 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 Efficiency
For 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 Design
The 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 Usability
Our 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 Trustworthiness
SNT 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.


 

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%.
