A sneak peak of the dBX shield valve in action.

Unheard-of safety and noise control.

Control valves don’t have to be loud. IMI’s all-new dBX Shield valve is the safest, quietest midstream control valve on the market. With the industry’s highest rangeability and unprecedented flow control, it essentially eliminates downstream vibration and can reduce noise to just 60 decibels (dBA). Its state-of-the-art DRAG™ technology controls high fluid velocity—delivering lower risk, lower noise, and lower maintenance costs for decades to come.


1,000:1 rangeability

As low as 60 dBA

30–50% less noise

Up to 99% less valve vibration

Don’t just bury the problem.

Over time, uncontrolled vibration from excessive noise and velocity can lead to hearing damage, valve failures, and gas leaks. The dBX Shield valve addresses the problem at the source—with velocity and fluid pressure (kinetic) energy control. Its innovative geometry and wide rangeability can reduce pipeline noise down to just 60–85 dBA—even at low flow rate high differential pressures. So you don’t have to mitigate excessive noise and vibration by burying the valve deep in the ground or building a barrier around it. From pipeline operators to nearby neighborhoods—everyone wins.

Engineered for your operating conditions.

No two pipelines are exactly the same. That’s why we work with you to custom engineer each valve based on your unique operating conditions. Only IMI has the engineering experience to control fluid velocity and its resulting vibration. We can adapt the dBX Shield valve to meet your precise flow rate specifications, health and safety requirements, environmental regulations, and much more.

The strong, silent type.

We deployed the first iteration of the dBX Shield valve more than 15 years ago. And it’s still going strong today. Powered by cutting-edge DRAG™ velocity-control technology, the dBX Shield valve actively mitigates velocity, noise, vibration, and erosion damage, making it the quietest, safest, and longest-lasting valve in its class.
