3PC Forged Steel Full Bore Trunnion Mounted Flange Ball Valve

JOEPAI Valve has been deeply involved in the 3PC Forged Steel Full Bore Trunnion Mounted Flange Ball Valve market since 2003, the valve consists of three components, facilitating disassembly and maintenance. Internal parts can be replaced without dismantling the entire pipeline, significantly reducing maintenance time and costs. Joepai focusing on customized and export services for forged high-pressure valves, with rich OEM experience. In industrial applications involving harsh conditions such as high pressure, high temperature, or corrosive media, forged ball valves are often a more reliable choice than cast valves. Unlike most ball valves that use casting processes, forged valves significantly improve their structural strength and pressure resistance through a unique manufacturing method. Choose a forged ball valve for severe conditions where safety, reliability, and maximum strength are non-negotiable.

Product Features

• Forged Steel Material: The valve body, ball and stem are all made of high-quality forged carbon steel (A105) or forged stainless steel (F304, F316) , processed through precision forging to eliminate casting defects, ensuring high strength and good corrosion resistance.

• Ball valves using a trunnion (fixed) ball design offer significant advantages in high-pressure conditions, operational performance, wear resistance, and safety, making them suitable for a variety of complex operating conditions.

• Flange Connection: Adopts ANSI-standard flange connection for seamless docking with pipeline systems, featuring easy installation and reliable sealing.

• Reliable Sealing Performance: The valve seat uses PTFE ,PEEK or metal sealing materials to ensure zero-leakage sealing under high-pressure and high-temperature conditions.

• Fire-safe Design: Complies with API 607 fire safety standards, maintaining sealing performance even in extreme conditions like fires to ensure system safety.

• Anti-static and Blow-out Proof Stem Design: Equipped with anti-static devices and blow-out proof stems to enhance electrical safety and operational stability.

• Multiple Operation Modes: Optional manual operation or automated control such as pneumatic, electric, or hydraulic actuators to meet requirements of different application scenarios.

• Low Flow Resistance Design: The smooth internal flow passage reduces flow resistance, effectively lowering energy consumption and improving system efficiency.
