Structural Features
Duplex Stainless Steel Material: The valve body is made of ASTM A182 F51 duplex stainless steel, which combines the advantages of austenitic and ferritic stainless steels. It has high strength, good corrosion resistance, and resistance to chloride stress corrosion, making it suitable for various media.
Trunnion Design: Adopts a trunnion design where the ball is fixed via upper and lower trunnion points. This reduces axial displacement of the ball during operation, lowers pressure on the valve seat, extends the valve's service life, and reduces operating torque simultaneously.
Low Operating Torque: Equipped with precisely aligned bearings, it enables low-torque operation even under high-pressure conditions, ensuring flexible and labor-saving valve operation, suitable for manual or automatic operation.
Fire Safety Design: Compliant with API 607 and API 6FA standards, the valve can maintain sealing performance even in case of fire, preventing medium leakage and safeguarding the safety of personnel and equipment.
Anti-Static Device: Built-in anti-static device ensures electrical continuity, prevents static accumulation, and reduces the risk of fire and explosion.
Valve Stem Blowout Prevention Design: The valve stem adopts a blowout prevention design, which ensures operational safety even under high-pressure conditions and prevents the valve stem from being blown out.
Dual Sealing Design: A dual-sealing design is used at the valve body connection, ensuring no leakage under standard operating conditions while meeting the requirements of API 607 for extreme temperature changes or fire scenarios.
Pressure Relief Device: Equipped with a pressure relief device that can automatically release excess pressure in the valve cavity to ensure safe operation of the valve.
