Edition: 02.2016

Description
The inlet elementsTE-13-__ are employed to connect the
external P, T lines to the P, T channels inside the ED
elements of the Directional Valve Assembly and to connect
the LS line for inlet fl ow control. An LS controlled 3-way
compensator provides pressure compensated fl ow to the
ED elements of the Directional Valve Assembly, any excess
fl ow si bypassed to tank at LS pressure plus compensator
spring bias. When the ED elements are in neutral position,
the compensator bypasses the entire fl ow to tank at a
bypass pressure equal to the compensator spring bias. In
case the LS pressure reaches the relief pressure setting,the
compensator unloads to tank the entire fl ow at relief
pressure plus compensator spring bias The TE-13 can be
equipped with a NO or NC Solenoid Unloading VEI
Cartridge, which can be employed to unloads to tank the LS
signal and bypasses the entire fl ow to tank at a bypass
pressure equal to the compensator spring bias. The TE-13
is provided with non compensated bleed down orifi ce. The
TE-13-…. is made of zinc plated cast iron. The coil S8-356
must be ordered separately (refer to RE18325-90).

General properties: it must have
physical lubricating and chemical
properties suitable for use in
hydraulic systems such as, for
example:
Mineral oil based hydraulic
fl uids HL (DIN 51524 part 1).
Mineral oil based hydraulic
fl uids HLP (DIN 51524 part 2).
For use of environmentally

1) The maximum regulated fl ow on P1 line is related both to the
pressure drop of the ED valve assembled on the group and their
spools size.
