Description
The secondary fl angeable 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), fi tted with cross-over confi guration: 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).
