IP-PRZ-59-AM12 Pilot Operated Proportional, Pressure Reducing/Relieving, Slip-in type
DESCRIPTION
Special cavity, ange retained, slip-in proportional pressure reducing/relieving valve.
OPERATION
The IP-PRZ-59-AM12 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 3 is blocked and the
regulated port 2 is vented to port 1.
As current is increased, uid pressure is proportionally controlled at the regulated port 2. On attainment
of proportionally determined pressure at 2, the cartridge shifts to block ow at 3, thereby regulating
pressure at 2. In this mode, the valve also will relieve 2 to 1 at a variable value over the set
reducing pressure.
FEATURES
• Economical slip-in style
• Integral waterproof coil
• Ecient wet-armature construction.
• Hardened parts for long life.
HYDRAULIC SYMBOL
Flanged Retained Product.
The coil (12 Vdc) is an integral part of the valve and is
not serviceable.
Inlet pressure up to 50 bar.
Max regulated pressure can be increased up to 35 bar
(factory preset)
Tank Pressure level above zero is additive to the valves
expected reduced pressure value.
