16 Inch side entry ball valve


Soft Seat side entry ball valve


Wear Resistant side entry ball valve

Product Description

Product Description:

The body material of the Trunnion Ball Valve can be made of either Carbon Steel or Stainless Steel. Carbon Steel is known for its strength and durability, making it an ideal choice for heavy-duty applications. Stainless Steel, on the other hand, is known for its resistance to corrosion and high temperatures, making it suitable for use in corrosive environments.

The Trunnion Ball Valve can be connected to pipelines using Flanged, Butt Weld, or Socket Weld end connections. Flanged connections are commonly used in applications where quick and easy installation is required. Butt Weld connections are known for their high strength and are commonly used in high-pressure applications. Socket Weld connections are used in applications where a leak-proof connection is required.

The Trunnion Ball Valve is a trunnion type ball valve, which means that the ball is supported by trunnions on either end. This design allows for a smooth and efficient operation of the valve, making it ideal for use in high-pressure and high-temperature applications. The trunnion mounted design also ensures that the ball is always in contact with the seats, providing a tight seal and preventing leakage.

The Trunnion Ball Valve is a side entry valve, which means that the ball can be accessed from the side of the valve. This design allows for easy maintenance and repair, without the need to remove the valve from the pipeline. The side entry design also allows for the valve to be installed in tight spaces, where top entry valves may not be feasible.

Overall, the Trunnion Ball Valve is a reliable and durable valve that is well-suited for high-pressure and high-temperature applications in the Oil and Gas, Chemical, and Power Plant industries. Its trunnion mounted design, choice of body materials, end connections, and side entry design make it a versatile valve that can be used in a variety of applications.

The trunnion ball valve is available in full port and reduced port options. The full port option provides maximum flow capacity, making it ideal for applications that require high flow rates. The reduced port option is suitable for applications with limited space or lower flow rates.

The trunnion ball valve has an anti-static design that complies with API 608 standards. This design ensures safe and reliable operation in explosive or flammable environments. The anti-static feature prevents the buildup of static electricity, which can cause sparks and fires.

The trunnion ball valve is available with different end connections, including flanged, butt weld, and socket weld. The flanged option is suitable for applications that require easy installation and removal. The butt weld option is ideal for applications that require a permanent connection. The socket weld option is suitable for applications with limited space or accessibility.

The trunnion ball valve has different seat material options, including PTFE, RPTFE, and PEEK. The PTFE option provides excellent chemical resistance and low friction. The RPTFE option provides better wear resistance and higher temperature resistance. The PEEK option provides excellent mechanical and chemical properties, making it suitable for extreme environments.

The trunnion ball valve is a side entry ball valve that allows in-line maintenance and repair. This feature reduces downtime and maintenance costs. The trunnion ball valve is suitable for different applications, including oil and gas, petrochemical, chemical, and power generation.

A Trunnion Ball Valve is a type of quarter-turn valve that uses a ball to stop or allow flow through the valve. The ball is supported by trunnions, which reduce the operating torque of the valve and provide stability to the ball.

Q: What are the advantages of using a Trunnion Ball Valve?

Trunnion Ball Valves offer several advantages, including: low operating torque, high flow capacity, reduced wear on the ball and seat, and improved sealing performance. They are also suitable for high-pressure and high-temperature applications.

Q: What materials are Trunnion Ball Valves made of?

Trunnion Ball Valves can be made from a variety of materials, including carbon steel, stainless steel, and exotic alloys such as titanium and hastelloy. The choice of material depends on the application and the process fluid.

Q: What is the maximum pressure rating for Trunnion Ball Valves?

The maximum pressure rating for Trunnion Ball Valves depends on the size, material, and design of the valve. Typically, Trunnion Ball Valves can handle pressures up to 10,000 psi.

Q: What industries use Trunnion Ball Valves?

Trunnion Ball Valves are used in a wide range of industries, including oil and gas, petrochemical, chemical, power generation, and water treatment. They are suitable for a variety of applications, from high-pressure steam to corrosive chemicals.
