J-VALVES
Structural Features
Chrome-Molybdenum Steel Material: The valve body is made of ASTM A217 WC9 chrome-molybdenum steel, which has high strength and good corrosion resistance. It can resist the erosion of various chemical media and extend the service life of the valve.
Pressure Seal Design: Adopts a pressure seal design—sealing performance enhances as the system pressure increases, ensuring reliable sealing in high-pressure environments.
Swing-Type Structure: The valve disc adopts a swing-type design, enabling smooth opening and closing, reducing fluid impact, and is suitable for medium flow rate conditions.
Bidirectional Sealing: The unique sealing design ensures reliable sealing during both forward and reverse flow, effectively preventing medium leakage and ensuring the safe operation of the pipeline system.
Fire-Safe Design: Complies with the API 607 standard. Even in case of fire, the valve can maintain sealing performance to prevent medium leakage and ensure system safety.
Anti-Static Device: Equipped with a built-in anti-static device, which effectively prevents static accumulation, reduces the risk of fire and explosion, and is particularly suitable for controlling flammable and explosive media.
Compact Design: Small in size and light in weight, it is easy to install and integrate into existing systems, saving space.
Multiple Operation Modes: Can be equipped with manual, pneumatic, electric, or hydraulic actuators to achieve remote and automated control.
