In the world of industrial operations, storage tanks are crucial for holding everything from raw materials to finished products. Whether it’s chemicals, petroleum or water, these tanks need to be meticulously managed to ensure safety and efficiency. One of the unsung heroes in this complex system? Industrial valves. These seemingly simple components play a pivotal role in managing the flow and pressure of substances within storage tanks, ultimately safeguarding both the operation and the environment. Let’s delve into how different types of valves contribute to the safe and effective management of storage tanks across various industries.
Types of Valves and Their Functions
Safety Relief Valves
Safety relief valves, also referred to as pressure relief valves, are essential for maintaining safe pressure levels within storage tanks. In scenarios where pressure exceeds the set limit, SRVs automatically release excess pressure to prevent catastrophic failures. For instance, in a chemical storage tank, an over-pressurisation scenario might occur due to a chemical reaction. A safety relief valve ensures that the pressure remains within safe operational limits, protecting both the tank and surrounding infrastructure.
Ball Valves
Ball valves are widely used in various industrial applications for their durability and reliability. Featuring a spherical disc (the “ball”) with a hole through the middle, ball valves allow for precise control of fluid flow. In storage tank operations, ball valves are often used for on/off control of liquids and gases. Their robust design makes them ideal for handling high-pressure applications, such as in the storage of high-pressure gases.
Actuators
Actuators are devices that control the operation of valves by converting energy into mechanical motion. At AC Valve Alliance, we offer pneumatic and scotch yoke actuators for tank storage terminals. Pneumatic actuators use compressed air to operate the valve, providing reliable and precise control. Scotch yoke actuators use a mechanical linkage to convert rotary motion into linear motion, ideal for applications requiring high torque. Our in-house automation department can provide the full valve package by integrating the actuator with the valve, ensuring a seamless and efficient operation.
Plug Valves
Plug valves, such as those manufactured by leading valve brand Galli & Cassina, are notable for their ability to provide tight shutoff and regulate flow with minimal pressure drop. They operate using a cylindrical or tapered plug with a passage through it, which rotates within the valve body to open or close the flow path. In the context of storage tanks, plug valves are frequently used in applications requiring high shutoff capability and reliable performance, such as in chemical or petrochemical processing. Their simple design and robust sealing make them ideal for isolating sections of a system or managing flow in applications where space is limited.
Butterfly Valves
Butterfly valves offer a compact design and are known for their quick operation. They are particularly useful in situations requiring precise flow control with minimal pressure drop. For instance, in a water treatment plant, butterfly valves can regulate the flow of water into and out of the storage tanks, ensuring efficient and accurate distribution.
Line Blind Valves
Line blind valves, also known as line blanks or blinds, are used to create a physical barrier in a pipeline, effectively isolating sections of the system. These valves are crucial for maintenance and safety procedures, as they allow for safe inspection or servicing by completely blocking the flow of fluids. In storage tank operations, line blinds are employed to ensure that specific sections of the pipeline can be isolated without disrupting the entire system. This ensures safe and efficient maintenance, reducing the risk of leaks or accidental release of stored materials.
Safety Considerations
Regular Maintenance
No matter how advanced the valve technology, regular maintenance is key to ensuring optimal performance and safety. Routine testing and inspections can prevent issues such as leaks, wear and tear or malfunctioning mechanisms. For instance, ensuring that PRVs are regularly tested and calibrated can prevent unexpected failures and maintain safety standards. High-quality brands like Starline and Air Torque offer reliable valves that, when maintained properly, can significantly enhance operational safety.
Proper Installation
Correct installation is crucial for valve performance and safety. Improper installation can lead to leaks, ineffective operation and even dangerous malfunctions. Valves from leading brands such as Nacional, Perar and Galli & Cassina come with detailed installation guidelines that should be strictly followed. Ensuring that valves are installed according to these manufacturer guidelines and industry standards will contribute significantly to the safety and efficiency of storage tank operations. Brands like Cassina and Bernard also emphasise the importance of professional installation to achieve optimal performance and reliability.
Compatibility with Stored Substances
Different substances require different types of valves. For example, corrosive chemicals may need valves made from specialised materials to resist degradation. It’s important to select valves that are compatible with the specific properties of the substances stored in the tanks to avoid damage and ensure longevity.
In Conclusion
In summary, industrial valves are integral to the safe and efficient operation of storage tanks across various industries. From regulating pressure with SRVs to preventing backflow with check valves, each type of valve serves a critical function in maintaining the integrity of storage systems. By prioritising regular maintenance, proper installation and selecting the right valve for the job, industries can ensure that their storage tanks operate safely and efficiently, protecting both their assets and the environment.
