Crafted with unmatched precision, the ball and seat of these valves boast reinforcement with advanced hard coatings, such as chrome carbide or tungsten carbide. This superior fortification ensures exceptional resistance to both erosion and abrasion, significantly enhancing the longevity and reliability of the valves. Our commitment to quality means you receive a product built to withstand the test of time.
Our SNT High Performance Soft Seated Ball Valves are enhanced with a state-of-the-art HVOF coating system, ensuring durability and efficiency. Each valve undergoes meticulous mate-lapping with proprietary techniques that guarantee flawless 100% sealing. The innovative live loading feature guarantees zero emissions, maintaining constant ball-to-seat contact for effective contaminant removal. This cutting-edge self-cleaning mechanism prevents interference and damage from particles, making these valves the premier choice for slurry and abrasive service applications.
Our expertly designed anti-blowout feature ensures the stem remains securely intact, preventing potential damage from unintended blowouts.
The innovative seat ring structure, featuring a wave spring and dual-scraper, effectively cleans the ball surface, maintaining optimal sealing integrity.
Our dual-sealing mechanism guarantees superior leakage control by ensuring the flow does not come into contact with the spring.
The intelligent draining and sweeping design effectively prevents valve jamming by thorough cleaning.
Compliant with API 607 standards, this product boasts exceptional fireproof and anti-static capabilities.
Their Remarkable Features Include:
A streamlined design that ensures effortless disassembly for your convenience.
Our ball valves are designed with maintenance ease in mind, featuring a non-tight fit design that facilitates swift servicing, reducing downtime during scheduled maintenance intervals.
State-of-the-art sealing technology for unparalleled security.
The multi-layer sealing system of the stem and body offers dual protection, combining O-ring and graphite or PTFE, which guarantees exceptional sealing efficiency and reliability.
This groundbreaking design complies with the stringent TA-Luft/Shell SPE 77/312 standards, ensuring top-tier performance.
Prolonged Service Life for Outstanding Cost-Efficiency
Our metal seated ball valves undergo sophisticated processing methods such as spray welding, spraying, and fusion welding. These processes ensure a hardness range of HRC58-73 and a binding force of 80-40MPa, delivering an impressive on-off cycle lifespan exceeding 100,000 operations with a leakage class of ANSI VI.
Innovative Modular Design for Enhanced User Convenience
The modular inner sealing design provides easy interchangeability between soft and metal seats, ensuring both flexibility and robust reliability to meet varying requirements.
Diverse Connection Types for User-Friendly Integration
Our valves are offered in multiple connection types, including flanged (RF, FF, FM, G, RJ), screw-thread, and BW. All types adhere to international standards, enabling seamless and user-friendly integration into any system.
