Accumulator Dump Manifold

The main functions of the ADM are:
– to dump the Hydraulic Accumulator on the pressure line connected with ADM, with manual or electrical command.
This function is performed by the Solenoid valve (SV) integrated that is a Normally Close (N.C.) valve.
– to allow system pressure decrease toward Return line in case of system over pressure, by means of the Thermal Relief Valve (TRV) integrated.
The TRV integrates also a filtering function by means of a screen installed in the same sub assembly. The filter screen cannot be replaced without replacing the whole valve within overhaul.
