Introduction
Our products are pipeline valves widely used in high pressure, high temperature and harsh working conditions. Forged Steel Trunnion Ball Valve is particularly suitable for the fields of petroleum, chemical, natural gas, electricity, etc.
Features
High sealing performance
The ball and sealing seat of our product is designed with precise matching, which effectively avoids the risk of fluid leakage. In particular, the special sealing material used can maintain a good sealing effect under high temperature and high-pressure environment, thereby ensuring the stability and safety of the system.
Anti-fatigue performance
Our ball valve is made of forged steel and is precisely processed, so its structure is tighter and stronger. This makes the valve have higher fatigue resistance and can maintain long-term stability even under high-frequency opening and closing operations.
Precise fluid control
The Forged Steel Trunnion Ball Valve can achieve precise control of fluids through precise ball design. The rotation of the ball is precisely adjusted by the drive device, which can effectively control the flow and direction of the fluid. Its unique three-way structure can not only realize the distribution and confluence of fluids but also switch between different flow directions, which is suitable for complex pipeline systems.

FAQ
Q: What is a Forged Steel Trunnion Ball Valve?
A: A Forged Steel Trunnion Ball Valve is a type of ball valve where the ball is supported by trunnions (upper and lower pivot points). It is made of forged steel, which enhances its strength and durability, making it suitable for high-pressure and high-temperature applications.
Q: What are the main applications of Forged Steel Trunnion Ball Valves?
A: These valves are widely used in industries such as oil and gas, petrochemical, power generation, and water treatment for applications involving high-pressure pipelines, corrosive media, and critical shut-off functions.
Q: How does the trunnion design improve valve performance?
A: The trunnion design reduces the torque required to operate the valve, especially in high-pressure systems. It ensures better sealing and stability as the trunnions support the ball, preventing excess movement and minimizing wear on the sealing components.
Q: What are the key materials used in Forged Steel Trunnion Ball Valves?
A: The body and ball are made of forged steel, such as ASTM A105, A350 LF2, or A182 F316. The seat and seals typically use materials like PTFE, PEEK, or metal alloys, depending on the application and media.
Q: What sizes and pressure classes are available for Forged Steel Trunnion Ball Valves?
A: They are available in a wide range of sizes, typically from 2 inches to 48 inches, and pressure classes ranging from ANSI 150 to ANSI 2500 or higher, depending on the design.
Q: What is the difference between a trunnion-mounted and a floating ball valve?
A: In a trunnion-mounted valve, the ball is fixed and supported by trunnions, making it suitable for high-pressure applications. In contrast, a floating ball valve has the ball free to move, which relies on the pressure to create a seal but is limited to lower pressure applications.
Q: How is the Forged Steel Trunnion Ball Valve sealed?
A: It uses a combination of soft or metal seats and sealing rings, with options for primary and secondary sealing. Some designs include self-relieving seats to handle thermal expansion and overpressure.
Q: What are the advantages of forged steel in trunnion ball valves?
A: Forged steel offers high strength, excellent resistance to pressure and temperature fluctuations, superior toughness, and a uniform grain structure, making the valve durable and reliable under harsh conditions.
Q: What maintenance is required for a Forged Steel Trunnion Ball Valve?
A: Regular maintenance includes checking for leaks, inspecting the seals and seats for wear, and ensuring the trunnion and ball mechanisms are well-lubricated and free of debris. Periodic testing of the valve's operational efficiency is also recommended.
Q: What standards and certifications are commonly followed for these valves?
A: Forged Steel Trunnion Ball Valves typically adhere to standards such as API 6D, ASME B16.34, ISO 5211 for actuation, and NACE MR0175 for sour service. Compliance ensures reliability and suitability for industry-specific applications.
