IP-DAR-43-C Direct Acting Proportional, Pressure Reducing/Relieving, Slip-in type
DESCRIPTION
Special cavity, slip-in style flange retained, direct acting proportional, pressure reducing/relieving valve.
OPERATION
The IP-DAR-43-C generates a variable pressure in response to a PWM (Pulse Width Modulated) current
signal. With no current applied to the proportional solenoid, the inlet port 2 is blocked and the regulated
port 3 is vented to port 1.
As current is increased, fluid pressure is proportionally controlled at the regulated port 3. On attainment of
proportionally determined pressure at 3, the cartridge shifts to block flow at 2, thereby regulating
pressure at 3. In this mode, the valve also will relieve 3 to 1 at a variable value over the set reducing
pressure.
FEATURES
Slip-in style
Efficient wet-armature construction
Integral waterproof coil
Continuous duty rated solenoid
HYDRAULIC SYMBOL
Flanged retained product.
The coil is an integral part of the valve and is not
serviceable.
Tank Pressure level above zero is additive to the valves
expected reduced pressure value.
