Forged Steel Fully Welded Ball Valve with Sleeves

Structural Features

• Fully Welded Structure: The valve body adopts a fully welded process, eliminating external bolts and flange connections, reducing potential leakage points, and enhancing the overall strength and sealing performance of the valve.

• Sleeve Design: Sleeves are equipped at both ends to ensure that welding operations do not affect the sealing materials, thus enhancing the valve's sealing performance and operational stability.

• Fire-Safe Design: Compliant with API 607 standards, the valve maintains sealing performance even in case of fire, preventing medium leakage and ensuring system safety.

• Anti-Static Device: A built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion, and is particularly suitable for controlling flammable and explosive media.

• Emergency Seal Injection: Equipped with an emergency seal injection port, it allows for quick repair in case of leakage, ensuring the valve's reliability and safety.

• Multiple Operation Modes: Can be equipped with manual, pneumatic, electric, or hydraulic actuators to achieve remote automated control.

• Compact Design: Small in size and light in weight, it is easy to install and integrate into existing systems, saving space.
