Your hydraulic valve might be fast… but is it fast where it actually counts? 👀

Here's the thing: Bigger numbers on a datasheet don't always mean better performance for your machine.

A valve that's too slow can hurt precision and cycle times. One that's more advanced than your application needs? You're paying for performance you may never use.

Our October Pilothouse is here to help you find that sweet spot!

We're breaking down:
🔹 What valve performance specs actually mean
🔹 How Continental Hydraulics' five proportional valve series compare
🔹 Why the fastest valve isn't always the best fit

Plus, we've included real performance data and comparison charts to help you make smarter valve selections.

Don't just buy the specs. Understand what they mean for your application.

Where it moves. How fast it moves. How much force it applies. Every detail matters.

This month’s Vendor Spotlight is Delta Motion, whose RMC motion controllers bring precise position, velocity, and pressure/force control to demanding hydraulic and electric servo applications.

Delta brings the control technology. Donald Engineering Company Inc. brings the application knowledge, system integration, and technical support to help turn that capability into a working solution.

Have a motion-control challenge? Bring us the application; let's tackle the challenge together.

“Just move it” isn’t the assignment.

Right position. Right force. Every cycle.

September’s Pilothouse gets into the engineering behind controlling both, and why it matters when you’re pressing, assembling, or moving a load.

Featuring Delta Motion, Exlar, SCHUNK USA, and Applied Motion Products, this is your peek at what happens when motion control gets the full team treatment.

Your machine moves. But how well does it control?

We’re cheering on Owen Haveman, son of our Technical Sales Engineer Bryan Haveman, after an incredible two-sport stretch for Grand Haven!

Owen helped secure a football win in his varsity debut, then turned around less than 24 hours later and scored three goals for a soccer victory.

Being a family-owned company means celebrating the families behind our team, too. We’re proud to recognize Owen’s hard work and an awesome accomplishment for the Haveman family.

Way to go, Owen!
