Hyvair pilot operated relief valve with adjustment knob and side port configuration

Pilot Operated Relief Valves

Pilot operated relief valves protect hydraulic systems from overpressure by using a small pilot stage to control a larger main poppet. This two-stage design provides more stable pressure regulation and handles higher flow rates than direct-acting relief valves, making pilot operated models the standard for main system relief.

What Actually Matters

Geography is just logistics. Brand names are just labels. What actually matters is this: when your equipment goes down, you need someone who understands what that means. Not someone reading from a catalog.
Someone who’s been there.

We’ve been there.

Real people answer the phone who can actually help solve problems.

We know what downtime costs because we’ve lived it.

When hydraulics fail, you need parts from someone who gets it. We do.
