J-VALVES-GV-1551
J-VALVES
8481804090
Structural Features
Carbon Steel Material: The valve body is made of ASTM A216 WCB carbon steel, which has high strength and good corrosion resistance, suitable for various media and working conditions.
Flanged Connection: Both ends adopt an RF (Raised Face) flanged connection method, compliant with ASME B16.5 or ASME B16.47 standards, ensuring easy installation and tight sealing.
Gearbox Operation Mechanism: Equipped with a gearbox operation mechanism, it enables labor-saving and stable operation, suitable for manual operation, and is particularly applicable to large-diameter or high-pressure valves.
Rising Stem Design: The valve stem adopts a rising design—during operation, the stem rises together with the valve gate, intuitively indicating the on-off state of the valve and ensuring operational safety.
Valve Gate Sealing: The valve gate adopts a flat sealing design, providing excellent sealing performance and ensuring reliable operation of the valve under high-pressure working conditions.
Fire Safety Design: Compliant with API 607 and API 6FA standards, the valve can maintain sealing performance even in case of fire, safeguarding the safety of personnel and equipment.
Anti-Static Device: A built-in anti-static device ensures electrical continuity, prevents static accumulation, and reduces the risk of fire and explosion.
Compact Design: With small size and light weight, it is easy to install and maintain, making it suitable for occasions with limited space.
