Engineered with unrivaled precision, the ball and seat components of these valves are bolstered with state-of-the-art hard coatings of either chrome carbide or tungsten carbide. This exceptional reinforcement provides superior resistance against both erosion and abrasion, significantly enhancing the longevity and dependability of each valve.
Our SNT High Performance Soft Seated Ball Valves feature a cutting-edge HVOF coating system. Each valve is subjected to meticulous mate-lapping through proprietary techniques to ensure impeccable 100% sealing. With an innovative live loading feature, these valves guarantee zero emissions, keeping the ball in constant contact with the seat to effectively eliminate contaminants. This advanced self-cleaning mechanism prevents particle interference and damage, making these valves the ultimate choice for slurry and abrasive service applications.
Ingeniously designed with an anti-blowout feature, our product prevents stem blowouts that could cause potential damage, guaranteeing the utmost safety and reliability.
The advanced construction of the seat ring, incorporating a wave spring and dual-scraper, is designed to meticulously clean the ball surface, maintaining impeccable sealing effectiveness.
Our dual-sealing innovation ensures exceptional leakage class integrity by preventing fluid contact with the spring, thus enhancing sealing assurance.
With a design focused on draining and sweeping, our product effectively prevents jamming by proficiently cleaning the valve, promoting seamless functionality.
Our product is fully compliant with API 607 standards, featuring robust fire-proof and anti-static capabilities for optimal safety and protection.
Their Remarkable Features Include:
An elegant, streamlined design that enables effortless disassembly, ensuring quick and easy access for any required maintenance.
Prioritizing the ease of upkeep, our ball valves boast a design that avoids tight fits, thereby facilitating swift servicing and minimizing operational downtime during regular maintenance procedures.
Pioneering sealing technology that guarantees maximum security and peace of mind.
With a multi-layer sealing approach for both stem and body, we offer dual protection using a hybrid of O-ring and graphite or PTFE, achieving outstanding sealing performance that stands the test of time.
This trailblazing design confidently meets the exacting standards of TA-Luft/Shell SPE 77/312, ensuring compliance and reliability.
Prolonged Service Life for Exceptional Cost Efficiency
Our metal seated ball valves are subjected to state-of-the-art processing techniques, including spray welding, spraying, and fusion welding.
