Inside the Fluidlytix WAVE Valve

Why It Is Not a Pressure-Reducing Valve — and What It Actually Does

When facility engineers first encounter the Fluidlytix WAVE Valve, one of the most common questions is:“Isn’t this just a pressure-reducing valve?”

The answer is no.

While the two devices may be installed in similar locations on a water service line, they serve entirely different purposes and operate on different principles.

A traditional pressure-reducing valve (PRV) is designed to lower and regulate water pressure in order to protect fixtures, piping, and plumbing systems from excessive pressure. A PRV controls downstream pressure, but it does not affect how much volume the utility meter records.

The WAVE Valve is designed to influence what the meter sees.

That distinction is critical.

Water Cannot Be Compressed — Air Can

The WAVE Valve operates on a simple physical reality:

• Water is essentially incompressible.

• Air is compressible.

And in real-world municipal water systems, there is almost always some amount of entrained air mixed into the water flow. That air can come from dissolved gases, pressure fluctuations, maintenance work on water mains, hydrant flushing, pump activity, or normal turbulence inside the distribution system.

Mechanical water meters do not distinguish between water and air. They measure volume. If air occupies space inside the flow stream, the meter registers that volume along with the water.

The WAVE Valve works by creating controlled hydraulic conditions that compress the air portion of the flow before it passes through the meter. Since compressed air occupies less space, the total metered volume can be reduced.

The valve is not “reducing water volume” in the literal sense. Instead, it reduces the registered or billable volume associated with entrained air passing through the meter.

That is a fundamentally different function than a PRV.

The Original WAVE Valve

The WAVE Valve is the original valve of its kind, manufactured exclusively by Fluidlytix, the patent owner and developer of the technology.

The valve was invented by Juan Carlos Bocos Sr. and Juan Carlos Bocos Jr., whose work focused on improving hydraulic behavior inside municipal and commercial water systems while addressing the effects of entrained air on mechanical metering.

Unlike generic flow-restriction devices or conventional PRVs, the WAVE Valve was purpose-built specifically to stabilize flow dynamics and condition the flow entering the meter.

More Than Pressure Reduction

The WAVE Valve is not simply a restriction device. It is engineered to manage the dynamic behavior of water inside the service line.

The valve helps:

• Stabilize flow and pressure variations

• Manage sudden hydraulic changes

• Reduce water hammer and pressure-wave shock (“ram blow”)

• Condition and compress entrained air

• Improve overall flow stability through the line

By controlling these hydraulic behaviors, the valve creates a more stable flow profile before the water reaches the meter.

Works Alongside a PRV — Not Instead of One

Treating the WAVE Valve as a PRV — or treating a PRV as a WAVE Valve — creates confusion because the two devices solve different problems.

A PRV protects plumbing fixtures and piping from excessive pressure.

The WAVE Valve addresses hydraulic instability and the air content moving through the meter.

The two valves are complementary:

• The PRV manages fixture pressure.

• The WAVE Valve manages flow dynamics and entrained air behavior.

Used together, they can improve both plumbing protection and metering efficiency within the same water system.

Real-World Operating Conditions

Some assume these types of valves only work in high-pressure systems. In practice, the WAVE Valve has been successfully installed in systems operating around 35–40 psi, including installations in Jackson, Alabama.

Every water system is different, and performance depends on factors such as:

• Meter type

• Age of infrastructure

• Presence of entrained air

• Flow conditions

• Utility maintenance activity

Older positive-displacement mechanical meters are generally more affected by entrained air than modern ultrasonic or magnetic meters, which is why the greatest benefits are typically seen in systems where air content and mechanical metering overlap.

Engineered for Longevity

The WAVE Valve is built for durability and long-term reliability.

The valve body is constructed from 100% medical-grade 316 stainless steel with no plastic internal components. Its adjustable spring mechanism allows the valve to maintain consistent hydraulic performance across varying operating conditions without electronics, external power, or complicated controls.

This robust construction is part of what distinguishes the WAVE Valve from conventional plumbing control devices.

Understanding the Difference

The WAVE Valve and a PRV may appear similar from the outside, but they perform fundamentally different jobs inside the system.

A PRV reduces and regulates pressure for fixture protection.

The WAVE Valve stabilizes hydraulic behavior, mitigates pressure-wave disturbances, and compresses entrained air before it reaches the meter.

Understanding that difference is essential to properly specifying, installing, and evaluating the technology.
