This document introduces the features and characteristics of proportional control and servo valves, including models, maximum operating pressure, and maximum flow rate.
This leaflet presents Tokimec's range of proportional control and servo valves, including direct‑acting relief valves (EPCG2 series), flow control valves (EPFG, EPFRG series) and 3‑way servo valves (ST3 series). It describes the operating principles, controller options, and the benefits of proportional hydraulic control such as smooth acceleration, shock‑less operation and system simplification.
The document provides performance curves, mounting dimensions, wiring diagrams, and detailed specifications for each valve model, along with installation notes such as air‑bleed procedures, manual pressure adjustment, and required mounting hardware.
| Maximum operating pressure (EPCG2‑01) | 21 MPa |
|---|---|
| Flow range (EPCG2‑01) | 0.3–1.5 L/min |
| Rated current (EPCG2‑01) | 1 A |
| Coil resistance (EPCG2‑01) | 14 Ω |
| Weight (EPCG2‑01) | 2.5 kg |
The EPCG2‑01 provides pressure adjustment ranges of 0.7–3.5 MPa, 1–7 MPa, 1–14 MPa, 1–17.6 MPa and up to 21 MPa depending on the selected code.
