Our engineering platform
ValveDyn Pro
Compressor valve dynamic calculation — engineering-grade simulation and precision modeling behind every valve we recommend.
What's inside the engine
Why our valve recommendations hold up
Most valve calculators give you a number. ValveDyn Pro tells you why — with transparent, defensible physics.
Dynamic ODE simulation
Full RK4 ODE solver on the valve plate — real lift, bounce count and impact velocity across the whole revolution, not a single-point flow check.
Four stability criteria
Costagliola hold-open, Frenkel flow-area sizing, Blevins flutter and 4-DOF resonance — cross-checked so a "healthy" score actually means something.
Wear & life prediction
Physics-based seat wear from Hertzian contact stress and Archard wear, calibrated against known reseat intervals.
Material selection engine
Feed it corrosive compounds, wet gas, liquids, solids and lubrication — it recommends ring, seat, spring and housing materials, and what it excluded and why.
Global optimizer
Sobol-sampled optimization of spring rate, lift and valve type across every stage of a multistage machine.
AI engineering assistant
Ask about your project in plain language — it answers from your actual computed results, not generic textbook advice.
One click to a client-ready PDF: parameters, per-stage performance, health scores and material recommendations — packaged automatically.
From software to parts
Engineering that turns into the right hardware
ValveDyn Pro isn't a stand-alone tool for us — it's how we make sure the valve, ring, spring and material we supply actually suit your compressor and your service. The result is fewer failures, longer intervals and parts you can trust.
- Valve selection defended by simulation
- Materials matched to your real conditions
- Clear, documented engineering reports
