DIN DN25 PN40 Stainless Steel Floating Ball Valves

Structural Features

• Stainless Steel Material: The valve body is made of 316 stainless steel, offering high strength and good corrosion resistance.

• Floating Ball Design: The ball can float freely under medium pressure, closely fitting the valve seat to achieve an excellent sealing effect.

• Flange Connection: Adopts DIN standard flange connection to ensure reliable installation and tight sealing.

• Fire-Safe Design: Complies with API 607 standards, maintaining 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: The stem features a blowout-proof design to ensure operational safety.

• Compact Design: Small in size and light in weight, facilitating installation and integration into existing systems.
