Structural Features
Carbon Steel Material: The valve body is made of ASTM A105 carbon steel, which has high strength and good corrosion resistance, suitable for various media and working conditions.
Fully Welded Structure: The valve body adopts a fully welded structure without flange connections, reducing the risk of leakage and ensuring the valve's sealing performance and durability.
Trunnion-Mounted Ball Design: Utilizes a trunnion-mounted ball design, where the ball is fixed by upper and lower support points. This reduces the axial displacement of the ball during operation, lowers the pressure on the valve seat, extends the valve's service life, and reduces operating torque simultaneously.
Electric Actuator: Equipped with an electric actuator, it provides precise remote control functionality, making it suitable for automated control systems with convenient operation and quick response.
Fire Safety Design: Compliant with API 607 and API 6FA standards, the valve can maintain sealing performance even in case of fire, safeguarding the safety of personnel and equipment.
Anti-Static Device: A built-in anti-static device ensures electrical continuity, prevents static accumulation, and reduces the risk of fire and explosion.
Stem Blowout Prevention Design: The valve stem adopts a blowout prevention design, which ensures operational safety even under high-pressure working conditions and prevents the stem from being blown out.
Compact Design: With small size and light weight, it is easy to install and maintain, making it suitable for occasions with limited space.
