Edition: 02.2016

Description
These modular secondary elements can be fl ange mounted
on top of the EDC elements machined with the interfacing
surface.
They let through free fl ow to the A (or B) port until pressure
increases and reaches the selected pressure setting; then
they release fl ow into the Tank channels.
The direct acting relief cartridges are designed for quick
response and stable pressure control; they also incorporate
a reverse fl ow 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.
