High pressure 2500LB Pneumatic Single Acting Spring Forged A105 Trunnion Ball Valve
Main Features
Stem Design: The valve stem is supported by bearings, which reduces the operating torque and improves the stability and reliability of the valve. It is especially suitable for large-diameter and high-pressure working conditions.
Pneumatic Single-acting Spring Actuator: Equipped with a pneumatic actuator that supports single-acting operation. When the air source fails, the spring can automatically return the valve to the safe position, ensuring the safety of the system.
Metal Sealing: Metal-to-metal sealing is adopted, which has higher wear resistance and high-temperature resistance, and is suitable for handling highly corrosive media.
Fire Safety Design: It complies with the API 607 fire safety standard and can maintain its sealing performance in extreme situations such as fires.
Anti-static Device: It has a built-in anti-static device to ensure electrical continuity among the valve stem, ball, and valve body, reducing the safety risks caused by static electricity.
Anti-blowout Valve Stem Design: The valve stem design includes a protective sleeve to prevent the valve stem from being blown out under high pressure.
Emergency Sealing Injection System: When the soft sealing material is damaged due to fire or other accidents, a sealant can be injected through the sealant injection device to provide additional sealing guarantee.
Double Block and Bleed Function: The valve has the double block and bleed function, which can block the flow of the medium from both sides simultaneously and release the pressure through the intermediate bleed port, ensuring safety during pipeline maintenance and inspection.
