RE 18300-19/06.2024, Bosch Rexroth AG
EDH Inlet Elements
with LS connections and double
pressure relief valve (P and LS line)
RE 18300-19
Edition: 06.2024
TEH-16
Description
The inlet elements TEH-16 are employed to connect the
external P,T lines to the P,T channels inside the EDH
elements of the Directional Valve Assembly and to connect
the LS ports of the elements equipped with LS channels.
They incorporate two pressure relief cartridge which limits
the maximum primary pressure in the P line and the
maximum load pressure in the LS line and unloads to tank
any excess flow.
The TEH-16 inlet elements are available with body made of
yellow zinc plated (Cr+3) cast iron (CI).
