Description

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

They incorporate two unidirectional flow restrictors, and, depending on the version selected (01 AB, or 02 AB), they allow free flow A1>A2 and B1>B2, with and controlled/ restricted flow in the reverse directions A2>A1 and B2>B1, or vice-versa.

Also the single acting versions are available, with only one flow restrictor fitted either in side A or in side B.

The restrictors are adjustable through the adjuster screw 3. The body of the EDM-VF- elements is made of Black Anodized Aluminium (AL). Hydraulic Ports A2 and B2 are size G 3/8.
