Forged Steel Gate Valve
J-VALVES
Cryogenic Design: The valve undergoes deep cooling treatment, capable of withstanding ultra-low temperature environments as low as -196℃, suitable for cryogenic media such as LNG and LPG.
Stainless Steel Material: The valve body, bonnet, and stem are all made of ASTM A182 F304 stainless steel, featuring excellent corrosion resistance and cryogenic toughness.
Flange Connection: Adopts RF (Raised Face) flange connection, conforming to ASME B16.5 standards, ensuring reliable installation and sealing performance.
Manual Operation: Equipped with a manually operated handwheel for easy opening and closing operations, especially suitable for on-site manual control.
Flexible Wedge Disc: Utilizes a flexible wedge disc design, which can compensate for the wedge angle deviation between the disc and the valve seat sealing surface, achieving an ideal sealing effect.
Fire Safety Design: Complies with API 607 standards, ensuring the valve maintains sealing performance even in case of fire to prevent medium leakage.
Anti-Static Device: Built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion.
Stem Blowout Prevention Design: The stem is designed with blowout prevention to ensure operational safety.
Compact Design: Small in size and light in weight, facilitating installation and integration into existing systems.
