DN500 600LB Pneumatic Forged Steel Flange Trunnion Ball Valve

Structural Features

• Forged Steel Material: The valve body is made of forged steel, providing high strength and good corrosion resistance. It can resist erosion from various chemical media, extending the valve's service life.

• Trunnion Design: The trunnion design ensures the stability and sealing performance of the ball under high pressure, reduces operating torque, and improves the valve's reliability.

• Pneumatic Actuator: Equipped with a high-performance pneumatic actuator, it enables fast and precise remote control and automated operation. The actuator offers multiple options, such as solenoid valves, limit switch boxes, filters, and E/P positioners, to meet different control requirements.

• 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: Built-in anti-static device effectively prevents static accumulation, reducing the risk of fire and explosion, especially 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.

• ISO 5211 Mounting Interface: The valve is designed in accordance with ISO 5211 standards, facilitating the installation and replacement of actuators, and improving system compatibility and maintenance convenience.
