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

EDCM/EDCMF-VM5

RE18301-47-prod
Description

These modular secondary elements can be flange mounted on top of the EDC elements machined with the interfacing surface.

They let through free flow to the A (or B) port until pressure increases and reaches the pressure setting; then they release flow into the Tank channels (T).

The maximum secondary pressure in line A, or B, can be adjusted through the adjuster screw (2).

The body (1) is made of Yellow Zinc Plated ( Cr+3) Cast Iron (CI). Hydraulic Ports A2 and B2 are size G3/8 and G1/2; with the modular version (M) is possible to flange the others type of EDCM-modular-elements avaible..
