Servo valves are the most precise component in a hydraulic control loop, which also makes them the most sensitive to wear, contamination, and electrical drift. When a machine starts behaving erratically, the servo valve is often blamed last and diagnosed least — even...

Proportional and servo valves both convert an electrical signal into precise, variable hydraulic flow or pressure, and from the outside they can look nearly identical. But the internal construction, tolerances, and intended application are different enough that using...

The amplifier card is the electronic bridge between your control system and the servo or proportional valve — and it’s one of the most overlooked components when a hydraulic system starts acting up. Because a failing amp card can produce symptoms that look...

Rexroth’s 4WRPE and 4WRPH series are both high-performance proportional/servo valves built around onboard electronics, and at a glance the model numbers alone don’t tell you much about which one belongs in your system. The difference comes down to control...

Rexroth proportional valves — including the 4WRA, 4WRZ, and 3DREP series — are built to handle demanding industrial and mobile hydraulic duty, but like any precision component they have predictable points of failure. Knowing where to look first can save significant...
