Industrial systems often rely on globe valves for precise flow regulation, but excessive noise can indicate underlying issues and lead to long-term operational damage. Whether you’re dealing with a high-pressure steam system or a complex chemical process line, globe valve noise is more than just an annoyance; it’s a performance and safety concern.
This guide walks you through practical globe valve noise attenuation techniques, helping you understand causes, control methods, and when to upgrade or consult with engineering professionals. Explore how the right approach can enhance system efficiency and prolong equipment life.
If you’re curious about our broader industrial solutions, our products page showcases a range of high-performance brands like Fisher and Bray that prioritise acoustic optimisation in their valve designs.
Noise in a globe valve is typically a symptom of turbulence or pressure fluctuations, often caused by improper sizing or unsuitable system configuration. Left unchecked, this can result in vibration, erosion, and even mechanical failure.
Beyond operational impact, valve noise can affect workplace comfort and occupational safety. Understanding the core causes is the first step toward effective noise attenuation.
When flow passes through a restricted valve seat, sudden changes in velocity and direction create turbulence. In high-pressure applications, this results in cavitation or flashing, two primary sources of valve noise.
Improperly sized globe valves exacerbate noise. A valve that’s too large may not control flow precisely, leading to cavitation and water hammer, while an undersized one forces excessive pressure drop, resulting in high-velocity flow and increased turbulence.
Common contributors include:
These conditions can be resolved through better engineering design and performance modelling, such as solutions offered by control valve experts like Fisher.
Reducing globe valve noise involves engineering solutions, retrofits, and improved system planning. From internal trims to advanced flow conditioning, various techniques offer both short- and long-term relief.
Specialised trims designed for noise reduction are a common and effective solution. These trims reduce turbulence by guiding flow more gradually, often through multi-stage pressure reduction or flow division, which dissipates energy more efficiently and prevents the high-velocity jets that generate noise.
Top benefits of low-noise trims:
Manufacturers such as Bettis and Bray often integrate such designs for industrial reliability.
In high-pressure systems, sudden pressure drop is the biggest contributor to noise. Staging this drop across multiple devices or system segments minimises acoustic issues by gradually dissipating energy, preventing the rapid formation of vapour bubbles (cavitation) and the subsequent violent collapse that generates significant noise and can damage equipment.
Techniques include:
Industrial applications using globe valves in critical environments often benefit from system-wide conditioning, not just valve-level fixes.
Apart from internal mechanics, external factors such as valve materials and installation methods greatly influence noise levels. Selection should match not only the flow type but also the ambient and mechanical conditions.
Valves constructed with stainless steel or other dense alloys tend to dampen sound better than lighter materials. Additionally, wall thickness and bonnet design can impact noise radiation.
Best practices:
Where and how a globe valve is installed can affect its acoustic behaviour. Valves too close to pumps, elbows, or other fittings tend to experience more turbulence.
