Product Overview

SV1‑10/48/315/6 is EMG direct‑drive electro‑hydraulic 4/3‑way proportional servo valve. It converts analog electrical command signal into precise hydraulic flow output without pilot‑stage oil supply, delivering robust high‑dynamic performance under heavy industrial conditions. Widely used in steel‑plant rolling mill gap‑control, heavy press equipment and material‑handling hydraulic closed‑loop control circuits. Discontinued legacy spare component; surplus and refurbished tested units for metallurgy‑plant hydraulic‑system overhaul and maintenance projects.

Application Notes

‑ Require clean hydraulic fluid meeting ISO 4406 cleanliness standards; filtration is mandatory. ‑ Respect manifold mounting torque specifications during installation. ‑ Perform closed‑loop tuning after valve replacement. ‑ Typical deployment: heavy‑industry hydraulic servo‑valve spare‑part stocking.
