AM3RD and AM3SD valves are direct acting spool type pressure reducing and sequencing units, respectively,
with one end pre-loaded by means of a spring an the other end exposed to
the hydraulic pressure.
The drainage is drained within the valve to port T. Pressure is adjustable
by means of a screw and locknut, or of a handwheel.Three types of springs
allow adjustment within the range 2÷250 bar. The pressure reducing valves are available in two versions:
with positive overlap (suitable with low flow rate) and with negative overlap to
obtain a greater pressure reinstatement speed.
