The proportional pressure reducing
valve PDMC05S30A is a direct-acting
spool-type valve. When de-energized,
port 2 is closed and port 1 (consumer) is
connected to port 3 (tank). When the inlet
pressure uctuates it provides an almost
constant outlet pressure - depending
on the energization of the coil. When the
control current increases, the coil solenoid
exerts a force on the control piston which
is proportional to the control current and
thereby denes the regulated pressure at
port 1. This setting is proportional to the
control current. Pressures at tank port 3
are additive to the set pressure. If, as a
result of external factors, the pressure at
port 1 rises above the preset pressure, the
valve opens from port 1 to tank port 3.
