Benefits of Trunnion Ball Valve
High-pressure rating:
The trunnion design allows them to handle significantly higher pressures compared to floating ball valves.
Reliable shut-off:
The positive sealing mechanism ensures a leak-proof closure, which is critical for applications where safety and environmental concerns are paramount.
Durability:
The robust construction with superior materials makes them resistant to wear and tear, ensuring a long service life.
Low maintenance:
Trunnion ball valves generally require minimal maintenance due to their simple design and high-quality components.
Quick operation:
The quarter-turn operation allows for rapid opening and closing of the valve, which is essential for emergency shut-off situations.
Versatility:
Trunnion ball valves are available in a wide range of sizes and materials, making them suitable for diverse applications.
Application of Trunnion Ball Valve
Oil and gas industry
Trunnion ball valves are common in oil and gas industry upstream, midstream and downstream activities. Pipeline transportation, refining processes, storage tanks, wellhead control etc. use them. These valves can withstand the high pressures and temperatures that are usual with this kind of work.
Petrochemical industry
Petrochemical plants heavily rely on trunnion ball valves to direct the flow of diverse chemicals and hydrocarbons around their system. Cracking, reforming isothermally or adiabatically operated distillation stills or batchwise distillation process and polymerization stages constitute some of these processes. In petrochemical environments that tend to escalate into harsh corrosive atmospheres, the resilient nature of trunnion ball valves makes them ideal for such situations.
Power generation
Fossil fuel power plants including nuclear power stations as well as renewables have applications for trunnion ball valves. They regulate the flow of steam, water and other fluids in boiler systems (e.g., economizers), cooling circuits (e.g., wet-surface air coolers) or steam turbine control systems (gland condensers). The ability of these Valves to handle the high pressures and temperatures they operate under therefore remains an essential part towards effective power generation.
Water and wastewater treatment
Water treatment plants desalination facilities as well as waste water treatment systems employ Trunnion Ball Valves. They regulate fluid flow in different treatments including filtration excretory system disinfection sedimentation among others where fresh water brine chemicals sludge etc pass through different channels respectively.
Mining and minerals
Mining operations utilize trunnion ball valves when handling process fluids like abrasive slurries, plus chemicals among many others. The mining of minerals and metals is usually done through a combination of extraction, beneficiation and mineral processing where these valves have been installed in pipelines, flotation circuits as well as various process plants.
Chemical processing
Chemical industries employ trunnion ball valves in the production line to control the flow of acids, solvents, polymers, and other chemicals. These are required in reactors such as distillation columns and mixing tanks across different chemical manufacturing areas including storage facilities for their raw materials.
Components of Trunnion Ball Valve
Body
The valve body is the outer shell of the valve that holds all the internal components in place. It can be made of various materials such as stainless steel, carbon steel, or low-temperature carbon steel. The body is typically constructed with flanged, butt-welded, or threaded ends to connect the valve to the pipeline.
Ball
The ball is a rotating disk that starts or stops the flow of fluid or gas in the valve. It is usually made of materials such as stainless steel, carbon steel, or brass. The ball is designed with a hole in the center to allow fluid or gas to pass through when it is in the open position.
Seat
The seat is a ring-shaped component that surrounds the ball and ensures that it stays in place when the valve is in operation. It is typically made of soft or Teflon materials or metal materials such as stainless steel. The seat creates a seal between the ball and the valve body to prevent leakage.
Trunnion
The trunnion is an additional shaft that holds the ball in place and prevents it from moving from below. It is attached to the ball disk with the help of welded joints. The trunnion is usually made of stainless steel or carbon steel.
Stem
The stem connects the actuator to the ball and ensures that they move together. It is usually made of stainless steel, carbon steel, or brass. The stem is attached to the ball with the help of a ball joint or other connection methods.
Injection system
The injection system is present in the stem and seat area and acts as a partial seal to prevent leakage when it occurs. It is typically made of soft or Teflon materials and is designed to be replaceable.
1.Check and grease the trunnion system regularly. This will reduce friction and extend the life of the valve.
2.Inspect for any signs of corrosion or leaks. Look at the sealing surface, body, and stem. Fix any problems quickly.
3.Exercise the valve by rotating it open and closed regularly. This will dislodge any debris and keep it working properly.
4.Keep records of any maintenance done. Document inspection dates, lubrication, and repairs. This will help identify any issues.
