Description

The inlet elements TE-07-__ 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 to the LS ports of the elements equipped with LS channels. The main functions are: to provide LS controlled pressure compensated flow to the Directional Valve Elements, to limit the primary pressure in the P channels and to unload to Tank the inlet flow when all hydraulic operations must be inhibited, by de-energizing the VEI solenoid operated cartridge. They are available in two versions: TE-07-01-03-… suitable for fixed displacement pumps, and TE-07-02-03-… for variable displacement pumps. The TE-07-__ inlet elements are manufactured with body made of Black Anodized Aluminium (AL). Port sizes are G 1/2, with LS and M test points G1/4. NOTE: the mechanical locking of the 3-way pressure compensator can be supplied upon request.
