Compact Directional Valves - Non-compensated and Post-compensated - Flangeable elements ED Series

EDM-VM

RE18301-41-01
Description

The secondary flangeable elements EDM-VM-__ can be interfaced and bolted on top of the A and B ports of the ED elements of the Directional Valve Assembly.

The body (1) is made of black anodized aluminium, and it incorporates one or two direct acting pressure relief valves (2), fitted with cross-over configuration: the relief valve for line A releases the oil into line B and viceversa The maximum secondary pressure in line A, or B, can be adjusted through the adjuster screw (3).
