8" 900LB F304 3PC Cryogenic Trunnion Flange Ball Valve

Structural Features

• Three-Piece Design: The valve body is divided into three parts, facilitating maintenance and component replacement, reducing downtime, while enhancing the overall strength and sealing performance of the valve.

• F304 Stainless Steel Material: The valve body, ball, and stem are made of F304 stainless steel, which has high strength and good corrosion resistance, capable of resisting erosion from various chemical media and extending the valve's service life.

• Trunnion Flange Design: The unique trunnion flange design provides higher installation flexibility and stability, facilitating valve installation and maintenance.

• Cryogenic Sealing Design: Uses low-temperature sealing materials to ensure sealing performance in extremely low-temperature environments.

• 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.

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

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