Manual Operated DIN PN40 Integral Forged A105N RF Flange Gate Valve

Manual Operated DIN PN40 Integral Forged A105N RF Flange Gate Valve

Structural Features

• Forged Steel Material: The valve body is made of ASTM A105N carbon steel, with high strength and good corrosion resistance.

• Flange Connection: Adopts RF (Raised Face) flange connection, complying with DIN standards to ensure reliable and tight installation.

• Flexible Wedge Disc: Uses a flexible wedge disc design, which can compensate for the wedge angle deviation between the disc and the sealing surface of the valve seat, achieving an ideal sealing effect.

• Fire Safety Design: Complies with API 607 standards, ensuring that the valve can maintain 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.
