API608 3PC Trunnion Mounted Ball Valve
Design Features
Three-piece structure: The valve body is divided into three parts, facilitating installation, maintenance and replacement of internal components and reducing downtime.
Trunnion-mounted ball design: The ball is fixed by trunnions, reducing the operating torque and improving the stability of the valve under high-pressure conditions.
Bi-directional sealing: It provides bi-directional sealing function to ensure reliable sealing of the medium in both forward and reverse directions.
Fireproof design: It complies with the API 607 and API 6FA fireproof testing standards and is suitable for flammable and explosive environments.
Anti-static design: It complies with the anti-static requirements of API 608 to ensure safety when used in flammable environments.
Multiple sealing materials: It offers a variety of sealing material options, such as PTFE, RPTFE, PEEK, etc., to adapt to different media and temperature conditions.
Low leakage design: It is equipped with a sealant injection system, which can inject sealant when the seals are damaged to ensure the tightness of the valve.
Blowout-proof stem design: The stem is designed with a blowout-proof structure to ensure safety under high-pressure working conditions.
