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

TI-C2

Description

The sandwich plate design directional valve elements TI-C2- -… basically consist of a stackable housing with a 2 way compensator controlled by the LS pressure signal.

The normally open compensator maintains a constant pressure difference between the P1 (outlet) line and the LS pressure; the result is a constant oil flow to the P1 port for the downstream operators, independently from the working pressure.

The excess oil must be unloaded to tank through a relief valve.

The stackable housing is made of Yellow Zinc plated (Cr+3) Cast Iron.
