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

EDCM/EDCMF-VM

RE18301-45-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 selected pressure setting; then they release flow into the Tank channels.

The direct acting relief cartridges are designed for quick response and stable pressure control; they also incorporate a reverse flow check for anti-cavitation.

With a body made of zinc plated cast iron, these elements combine secondary pressure relief and dual cross-over, with anti-cavitation function.
