CPRV (Charge Pressure Relief Valve)
The charge pressure relief valve maintains charge pressure at a designated level above case pressure. The
charge pressure relief valve is a direct acting poppet valve which opens and discharges fluid to the
hydrostatic transmission case when pressure exceeds a designated level. For external charge flow the
CPRV is set according to below table. The charge pressure relief valve setting is specified on the model
code of the unit.
