Our valves boast a ball and seat that are expertly hard-coated with either chrome carbide or tungsten carbide. This treatment endows them with exceptional resistance to erosion and abrasion, ensuring durability and reliability in challenging environments.
At SNT Machinery (Qingdao) Co., Ltd., we employ a cutting-edge HVOF coating system, combined with our proprietary mate-lapping technique, to achieve impeccable 100% sealing. The live loading feature guarantees zero emissions, maintaining environmental integrity. The innovative design ensures that the ball continuously maintains contact with the seat, effectively wiping away any contaminants. This self-cleaning mechanism prevents potential interference and damage from contaminants, making these valves ideal for both slurry and abrasive service applications.
Key Features and Characteristics:
Ingenious, Simplified Structure for Quick Disassembly
Our valves are designed with ease of maintenance as a priority, featuring a non-tight fit design that streamlines periodic servicing, significantly reducing maintenance time.
Cutting-edge Sealing Solutions Ensuring Optimal Security
The multi-layered sealing system, combining O-ring and graphite or PTFE, provides a robust double sealing of the stem and body, enhancing reliability and durability.
This innovative design complies with TA-Luft and Shell SPE 77/312 standards, ensuring superior performance.
Extended Service Life for Enhanced Cost-Effectiveness
Our metal-sealed ball valves boast advanced processing techniques such as spray welding, spraying, and fusion welding for the ball and seat ring. This ensures a remarkable hardness range of HRC58-73 and a binding force of 80-40MPa. The valves are capable of exceeding 100,000 on-off cycles, maintaining an ANSI VI leakage class.
Convenience through Intelligent Modular Design
The inner sealing's modular design facilitates the interchangeability between soft and metal seats, providing versatile solutions tailored to specific needs.
Versatile Connection Types for Comfort and Usability
Offering a variety of internationally recognized connection types such as flanged (RF, FF, FM, G, RJ), screw-thread, and BW types, our valves ensure user-friendly and adaptable installations.
