About This Relief Valve

Swing (slewing) relief valves protect the swing circuit from shock loads during start and stop of the upper structure. Direct OEM-spec replacements.

The E307D SLEWING is an OEM-standard aftermarket replacement built to the original mounting, spline and port specification. Bolt-on installation — no machining or adaptation required.

Every unit is inspected and pressure-checked before dispatch and ships with a test report. Stock models leave within 48 hours; non-stock units are typically ready in 5–15 days. Sea, air and express shipping are available worldwide, and our team answers quote requests within 12 hours — usually much faster on WhatsApp.

How do I know which valve failed?

Typical symptoms: machine slow under load (main relief), travel drift or weak braking (travel relief), swing soft or over-swing (swing relief). Send the symptoms and machine model on WhatsApp and we point to the right valve.

Are these adjustable?

Main relief valves are pressure-adjustable like the originals; we ship them preset to the standard setting for the machine model.

Can I buy in bulk?

Yes — relief valves are a steady wholesale item. Ask for a mixed-container quote.
