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.
Bolted Bonnet: Adopts a bolted bonnet design, facilitating maintenance and overhaul while ensuring good sealing performance.
Flanged Connection: Both ends use a flanged connection method, compliant with the ASME B16.5 standard, ensuring convenient installation and reliable sealing.
Rising Stem Design: The valve stem adopts a rising design; during operation, the stem rises together with the valve disc, intuitively indicating the valve's open/closed state and ensuring operational safety.
Multiple Valve Disc Designs: Two valve disc designs—solid wedge and flexible wedge—are available. They can be selected based on different operating conditions to ensure excellent sealing performance.
Fire Safety Design: Complies with API 607 standards; even in case of fire, the valve can maintain sealing performance to protect 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: Despite being a large-diameter valve, it has a compact structure, which is easy to install and maintain, making it suitable for occasions with limited space.
