DBE(M)EDG pressure valve OVERVIEW

DBE(M)/EDG pressure valves are proportional pressure control valves. DBE(M) is pilot‑operated proportional relief valve; EDG is direct‑acting proportional relief valve. They realize stepless continuous pressure adjustment according to electric input signal. DBE(M) version can be equipped with mechanical over‑pressure safety protection. Integrated or external amplifier options are available. With ISO standard sub‑plate mounting, they feature high pressure control accuracy and good linear performance. Widely adopted for variable pressure setting in hydraulic test benches, injection molding machines and automated hydraulic power units.

Features and Benefits

• DBE(M) adopts pilot‑operated structure while EDG uses direct‑acting design, both provide excellent linear performance and low hysteresis for accurate proportional pressure control.

• Stepless pressure adjustment via analog electrical input signal enables flexible remote pressure setting to match varying cycle requirements of automated systems.

• DBE(M) version supports optional mechanical over‑pressure safety protection, offering double‑safety guarantee for hydraulic equipment.

• Integrated amplifier or external drive options accommodate different electrical cabinet layout demands.

• ISO standard sub‑plate mounting ensures high interchangeability with mainstream brand valves for convenient installation and replacement.

• Various pressure ranges and multiple signal types (0‑10 V, 4‑20 mA) fit global industrial control standards.

• Optional FKM seals support special hydraulic media to extend application scope.

• DBE(M) covers large‑flow conditions with NG10, NG20, NG30 sizes; compact EDG is optimized for small‑flow systems with fast‑response demands.
