Pressure Reducing Valve: Pilot Operated
We're working on the next.
Grab the controls. Power the solenoids.
Cause a pressure spike. See what happens.
This is industry-leading interactivity.
Follow the paths in series and parallel circuits.
Learn how to read complex electrical and hydraulic schematics.
Pressure and flow, current and voltage — we show you how they relate. Get grounded on the fundamentals!
Rushed & reckless repairs can be deadly.
Our lessons alert you to the risks and best practices. Check the hazards, and concentrate on working safely.
Let's put those pressure gauges, flow meters,
and multimeters in the right hands: yours. We teach you to be a top troubleshooter.
There are so many different components!
Sensors, valves, relays, accumulators, pumps...
See how they work, how they fail, and how to fix them. The days of mindless part-swapping are over.
Load sense? Yep!
Hydrostatic drives? Covered.
Complex valve banks with crazy centers? We give you guidance and tools for deep understanding.
Our learning content is always evolving.

Two words: very impressed. It is fast!
There is no waiting for things to work or load.
The animation is very effective.Patricia N. Syncrude
It is a fantastic way to understand
what is actually happening
in our hydraulic world.
