DN80 PN25 3PC Forged Steel Trunnion Flanged Ball Valves

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.

• Forged Steel Material: The valve body, ball, and stem are made of high-quality forged 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.

• Metal Sealing: The metal sealing design is suitable for medium and high-pressure environments, offering excellent sealing performance and maintaining zero leakage even under extreme working conditions.

• 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.
