J-VALVES
Super Duplex Stainless Steel Material: The valve body, ball, and stem are all made of super duplex stainless steel (e.g., 2507/S32750), which features high strength and excellent corrosion resistance, enabling long-term stable operation in harsh chemical environments.
Three-piece Design: The valve body is divided into three sections, facilitating easy maintenance and component replacement to minimize downtime. It also enhances the valve’s overall structural strength and sealing performance.
Trunnion Mounted Design: The ball is fixed to the valve body via trunnions, providing additional support to ensure smooth operation under high-pressure conditions and reduce the load on the valve seat.
Superior Sealing Performance: Equipped with high-performance elastic valve seats, it delivers outstanding bidirectional sealing performance, ensuring the valve maintains a tight seal under various operating conditions.
Fire-safe Design: Compliant with API 607 standard, the valve can retain its sealing performance even in the event of a fire, preventing medium leakage.
Anti-static Device: A built-in anti-static device effectively prevents static accumulation, reducing the risks of fire and explosion.
Stem Blowout Prevention Design: The valve stem incorporates a blowout-proof design to ensure operational safety and prevent the stem from being ejected due to medium pressure.
Compact Design: The overall structure is compact, saving installation space, and is particularly suitable for mounting environments with limited space.
Flanged Connection: Flanged connection is adopted to ensure reliable installation and excellent sealing performance, facilitating seamless integration with existing pipeline systems.
