LENOR Trunnion Mounted Ball Valves are a type of industrial valve that are designed to control the flow of fluids, such as liquids or gases, in a pipeline. They are called “trunnion mounted” because the ball within the valve is supported by trunnions, which are small shafts that extend from the valve body.

The main function of a trunnion mounted ball valve is to provide a tight shut-off and control the flow of fluids. They are commonly used in applications where high pressure, high temperature, or large flow rates are involved. The trunnion mounted design allows for increased durability and reliability, making them suitable for demanding industrial environments.

Some of the key industries that use trunnion mounted ball valves include:

  1. Oil and Gas: Trunnion mounted ball valves are widely used in the oil and gas industry for various applications, such as pipeline transportation, refining, and storage. They can handle high-pressure and high-temperature conditions, making them suitable for oil and gas exploration and production.
  2. Petrochemical: Trunnion mounted ball valves are also commonly used in the petrochemical industry for controlling the flow of various chemicals and gases. They are suitable for handling corrosive and hazardous substances.
  3. Power Generation: Trunnion mounted ball valves are used in power plants for controlling the flow of steam, water, and other fluids in the power generation process. They are designed to withstand high-pressure and high-temperature conditions.
  4. Water and Wastewater Treatment: Trunnion mounted ball valves are used in water and wastewater treatment plants for controlling the flow of water, chemicals, and sludge. They are designed to handle abrasive and corrosive substances.
  5. Mining: Trunnion mounted ball valves are used in the mining industry for controlling the flow of various fluids, such as water, chemicals, and slurries. They are designed to withstand harsh and abrasive conditions.

Overall, trunnion mounted ball valves are versatile and widely used in various industries where reliable and efficient flow control is required.

The trunnion mounted design of ball valves offers several benefits compared to other types of valve designs. Here are some of the key advantages:

  1. Increased Durability: Trunnion mounted ball valves are designed to handle high-pressure and high-temperature conditions, making them more durable and reliable. The trunnion support system provides additional stability to the ball, reducing the risk of deformation or damage under extreme operating conditions.

  2. Enhanced Sealing Performance: The trunnion mounted design allows for the use of larger and more robust sealing elements, such as O-rings or seat rings. This improves the sealing performance of the valve, ensuring a tight shut-off and minimizing the risk of leakage.

  3. Improved Flow Control: Trunnion mounted ball valves offer excellent flow control capabilities. The full bore design allows for unrestricted flow through the valve, minimizing pressure drop and turbulence. The ball is also designed to provide a smooth and precise rotation, allowing for accurate flow modulation.

  4. Lower Operating Torque: The trunnion mounted design reduces the operating torque required to open or close the valve. This is because the trunnions support the weight of the ball, reducing the friction between the ball and the valve body. As a result, trunnion mounted ball valves are easier to operate and require less energy.

  5. Versatility: Trunnion mounted ball valves can be used in a wide range of applications and industries. They are suitable for handling various fluids, including liquids, gases, and slurries. The robust design and materials used in trunnion mounted ball valves make them suitable for demanding environments, such as oil and gas, petrochemical, and power generation.

  6. Maintenance Friendly: Trunnion mounted ball valves are designed for easy maintenance. The trunnion support system allows for easy access to the ball and seat for inspection, repair, or replacement. This reduces downtime and maintenance costs.

Overall, the trunnion mounted design offers improved durability, sealing performance, flow control, and ease of maintenance, making it a preferred choice for many industrial applications.

Common maintenance practices for trunnion mounted ball valves include:

  1. Regular Inspection: Regular visual inspections should be conducted to check for any signs of wear, damage, or leakage. This includes inspecting the valve body, ball, seats, seals, and stem for any signs of corrosion, erosion, or mechanical damage.

  2. Lubrication: Proper lubrication is essential for the smooth operation of trunnion mounted ball valves. Lubrication helps reduce friction and wear between the ball and seats, as well as the stem and packing. Lubrication should be performed according to the manufacturer’s recommendations using the appropriate lubricant.

  3. Cleaning: Trunnion mounted ball valves should be cleaned periodically to remove any debris, scale, or deposits that may accumulate on the ball, seats, or body. This can be done by flushing the valve with a suitable cleaning solution or using mechanical cleaning methods.

  4. Seat Replacement: Over time, the seats of trunnion mounted ball valves may wear out or become damaged. If leakage is detected or if the valve fails to provide a tight shut-off, the seats may need to be replaced. This should be done following the manufacturer’s instructions and using compatible replacement parts.

  5. Stem Packing Replacement: The stem packing of trunnion mounted ball valves may require replacement if it becomes worn or damaged. This is important to ensure proper sealing and prevent leakage. The packing should be replaced with the appropriate type and size, following the manufacturer’s guidelines.

  6. Actuator Maintenance: If the trunnion mounted ball valve is equipped with an actuator, regular maintenance of the actuator is necessary. This includes checking the actuator’s condition, lubricating moving parts, and verifying proper operation.

  7. Calibration and Testing: Periodic calibration and testing of trunnion mounted ball valves may be necessary to ensure accurate flow control and proper functioning. This can include checking the valve’s opening and closing torque, verifying the seat tightness, and conducting performance tests.

It is important to note that maintenance practices may vary depending on the specific valve design, application, and manufacturer’s recommendations. It is recommended to consult the valve manufacturer’s documentation and guidelines for detailed maintenance procedures specific to the trunnion mounted ball valve being used.
