Proportional Directional Control Valve, with Digital Onboard Electronics and Internal Feedback
Technical Features
The proportional directional control valve PRM9 consists of a cast iron housing, a special control spool, two centering springs with supporting
washers, one or two proportional solenoids, a position sensor and a digital onboard electronic. The measurement system of the position sensor
is based on a differential transformer with a sensor core and its electronic evaluation unit.
The unit, containing the digital onboard electronics, is mounted on the valve housing. Due to this, the solenoids are able to be connected directly
to the electronics without any cabling at all. The connection of the position sensor to the control unit is provided by a cable.
For main contacting of the digital electronics, the MIL-C5015 (6 + PE) connector is available for connecting the supply, the setpoint signal and
monitor signal of the internal piston position. Other connection possibilities are directly related to the selected valve variant. These are, in detail,
M12x1, 5-pin, for the bus connection in the standard version CANopen and also M12x1, 5-pin, for connecting an external sensor (of an external
process variable).
The digital control unit utilizes pulse-with-modulation (PWM) and supplies the solenoids with current, proportionally to the control signal. The supply
current is additionally modulated with a dither frequency and an amplitude.
Further / individual functional parameters like ramp, offset, deadband, max. current, etc. can be adjusted with the PRM9 parametrization software.
Therefore, a standard computer can be connected with the valve by USB (USB-A (PC) ⇔ µ-USB (valve)).
The factory configuration is set individually for each valve. The configuration data file as well as the parametrization software and the fieldbus data
file can be downloaded from the ARGO-HYTOS website.
The PRM9 is available with following model options:
Models with standard OBE
E02S02 internal spool position feedback
E04S02 internal spool position and external feedback
Models with OBE and CANopen connectivity
E02S02-CA internal spool position feedback, CANopen connectivity
E04S02-CA internal spool position and external feedback and CANopen connectivity
All models are equipped with an optical feedback (standard: 2 LEDs; with CANopen: 3 LEDs). The flash code of the LED indicates the current status
of the valve (for further details see the operating manual of the valve). As a standard, the proportional valve is delivered with factory setting.
For a model including an external feedback (E04), contact the manufacturer for specific data.
Functional Description
› Direct acting proportional control valve with integrated digital onboard electronics (OBE),
proportional control, spool and process feedback
› Control valve with subplate mounting surface acc. to ISO 4401, DIN 24340 (CETOP 03)
standards
› The valve opening and resulting flow rate can be modulated continuously in proportion
to the reference signal
› Digital electronics allows fine control of the valve spool position, reducing hysteresis
and response time and optimizing the performance of the valve
› Used for e.g. position and speed control of hydraulic actuators
› Wide range of interchangeable spools available
› The settings of electronics can individually be adjusted by a parametrization software
› Easy to connect via USB ⇔ Micro-USB ports
› Optical feedback of valve status through three LEDs
› The valve is zinc-coated with the enhanced surface corrosion protection 520 h in NSS
acc. to ISO 9227
› High hydraulic power limits and smooth running characteristic
› Improved shock and vibration behavior
› CANopen connectivity

- For proportional valves with two solenoids, one solenoid must be de-energized before the other solenoid can be charged.
- Mounting bolts M5 x 45 DIN 912-10.9 or studs must be ordered separately. Tightening torque is 8.9 Nm (6.56 lbf.ft).
- Besides the shown, commonly used valve versions other special models are available.
- Contact our technical support for their identification, feasibility and operating limits.
