Large-size valves are strategic components in industries where fluids are handled on a large scale, under high pressure, or in extreme conditions. Their use is not only a functional requirement but also a matter of safety, energy efficiency, and operational reliability.
In this article, we analyze the main industrial sectors that require large-diameter valves and why the machining of these components must meet strict technical standards.
Why do some industries require large-size valves?
- Higher flow rates: Large-diameter valves are needed to handle high volumes of fluids or gases.
- Extreme conditions: Pressure, temperature, or aggressive substances demand robust and precise components.
- Critical processes: A valve failure can halt strategic operations or compromise safety.
🛢️ 1. Oil & Gas
In both upstream and downstream operations, these valves control the flow of oil, gas, or vapors under pressure. They are used in pipelines, refineries, pumping stations, and loading terminals.
🚢 2. Naval and Offshore
Large vessels, floating production storage and offloading units (FPSOs), and offshore platforms use large-size valves in cooling, ballast, propulsion, and discharge systems. These components must resist marine corrosion and be easy to maintain in remote environments.
🧪 3. Petrochemical Industry
Plants that process chemical products or natural gas require robust valves capable of withstanding aggressive substances, high temperatures, and continuous operation. Their design and machining must be adapted to the specific requirements of each process.
💧 4. Water Treatment
In water purification plants, wastewater treatment facilities, or large-scale irrigation systems, large-size valves ensure safe and efficient fluid flow. They are also essential in pumping stations and desalination plants.
❄️ 5. Cryogenics
Handling liquefied gases like oxygen, nitrogen, or helium requires large cryogenic valves that function precisely at extremely low temperatures. These valves must maintain thermal insulation and tight sealing.
⚡ 6. Power Generation
In thermal, hydroelectric, and combined-cycle power plants, large-size valves regulate the flow of steam, water, or gases in high-pressure systems. Their reliability is critical to avoiding unplanned shutdowns or accidents.
Why is the machining of these valves so critical?
Each sector imposes specific technical requirements: tight tolerances, resistant materials, anti-corrosive coatings, leak-proof performance… That’s why, at Asimer Group, we apply precision CNC machining, specialized welding, and rigorous quality controls to ensure the reliability of every valve, regardless of the environment where it is used.
