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 pressure setting; then they release
fl ow 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 fl ange the others type
of EDCM-modular-elements avaible..
