Engineered pressure-drop control

Make the butterfly valve do more.

The Max ΔP Cartridge adds a purpose-designed throttling element to any butterfly valve— improving control while managing pressure drop, velocity, cavitation, and noise.

Pressure-drop hardware

Built around the application.

Start with the valve, the cartridge, or the entire package. We engineer the pressure-drop solution around your actual operating conditions.

Engineering before hardware

The cartridge geometry comes from the calculation.

Our proprietary software evaluates the valve, fluid properties, pressure profile, required capacity, cavitation behavior, acoustic risk, velocity, and operating range together. That work defines the cartridge and resistance-plate geometry—not the other way around.

How we work

One application. One engineered answer.

01

Review

We review every operating case, the piping system, fluid properties, and performance concerns.

02

Model

Our software evaluates capacity, pressure staging, velocity, cavitation, noise, and control behavior.

03

Engineer

We define the cartridge, valve package, and any resistance plates the application requires.

04

Support

We stay involved through quotation, installation, commissioning, and troubleshooting.

Application request

Send us the pressure drop.

Give us what you have. A datasheet is ideal; a rough operating description is enough to start.
