Structural Features
CF8C Stainless Steel Material: The valve body is made of CF8C stainless steel, which offers high strength and good corrosion resistance, allowing long-term stable operation in harsh chemical environments.
Pressure Sealed Design: The unique pressure-sealed structure enhances sealing performance as the system pressure increases, effectively preventing medium leakage.
Swing-Type Structure: The swing check valve design ensures smooth opening and closing, reducing the impact of the medium on the valve and extending its service life.
Compact Design: The overall compact structure saves space, making it particularly suitable for installation environments with limited space.
Fire-Safe Design:Compliant with API 607 standards, the valve maintains sealing performance even in case of fire, preventing medium leakage.
Anti-Static Device: A built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion.
Stem Blowout Prevention Design: The stem adopts a blowout prevention design to ensure operational safety and prevent the stem from being blown out due to medium pressure.
Butt-Weld Connection: Uses a butt-weld connection method, which provides a firm connection with the pipeline system and excellent sealing performance, suitable for high-pressure and high-temperature working conditions.
