Proportional control mechanism
Proportional electromagnet: The input current signal (0-20mA) drives the electromagnet to generate linear displacement, and the position of the main valve core is controlled through the pilot valve.
Closed-loop feedback: The built-in LVDT displacement sensor monitors the position of the valve core in real time. After comparing with the command signal, it corrects the output to ensure high-precision control (hysteresis < 0.5%).
Regeneration mode: Optional hybrid version. Energy consumption can be reduced by switching the regeneration mode (such as the differential circuit of the hydraulic cylinder).
Pilot-operated structure
Pilot valve: Based on the Parker D1FB control valve, it adopts a valve core/sleeve design to provide stable pilot pressure control.
EtherCAT communication: Supports real-time parameter adjustment and status monitoring, compatible with the intelligent requirements of Industry 4.0.
3. Product features and advantages
Core features
High precision: The position feedback system ensures that the flow regulation accuracy reaches ±0.5%, making it suitable for precision processing.

Energy-saving design: The regeneration mode can reduce the energy consumption of the hydraulic system by 20% to 30%.
Diagnostic function: Provide preventive maintenance data through the EtherCAT interface to reduce downtime.
Reliability and durability
Wear-resistant structure: The surface of the valve core is hard chromium plated, with a service life of over 20 million times (refer to the same series of products).
Anti-pollution capability: The pilot-stage filtration accuracy is 10μm, suitable for harsh industrial environments.
4. Usage functions and purposes
Core function
Flow control: Continuously adjust the oil flow through proportional signals to achieve speed control of the actuator.

1. Installation and connection
Installation direction
It is recommended to install it vertically upwards to prevent foreign objects from depositing in the valve core assembly. If inclined installation is required, it is necessary to ensure that the movement of the valve core is not affected by pipeline stress and that there is no risk of liquid accumulation at the pilot oil port (X port).
The installation location should be far away from vibration sources and high-temperature equipment (such as hydraulic pumps and motors), and sufficient space should be reserved for maintenance.
Pipeline connection
Connect the main oil circuit and the pilot oil circuit correctly according to the valve body markings (P/A/B/T/X) to avoid reverse connection.
Use high-pressure hoses or steel pipes that meet standards and ensure that the pipelines are clean and free of burrs. It is recommended to install a 10μm filter (such as the Parker FH06 series) before the valve to prevent particle contamination of the pilot stage.
When tightening the pipe joint, the wrench should be placed close to the root of the joint to prevent the valve body from bearing torque.
Electrical wiring
Connect the M12×1 connector (4 pins) as per the instruction manual and ensure the correct polarity of the power supply (+24V DC).
Signal cables should be laid separately from power cables to reduce electromagnetic interference. It is recommended to use shielded cables and ground the shielding layer at one end.
If EtherCAT communication is enabled, a compatible master controller (such as the Beckhoff CX series) must be configured and the communication protocol version must be matched.2. Oil management
Medium selection
Use mineral hydraulic oil (such as ISO VG 46/68) or synthetic hydraulic oil, and avoid media incompatible with sealing materials (NBR/FKM).
The viscosity of the oil should be controlled within the range of 20 to 380 mm²/s, and the oil temperature should be maintained at -20℃ to + 60℃.
Cleanliness requirements
The cleanliness of the oil should meet ISO 4406:2017 18/15/12 or higher (particle count: >4μm ≤ 13,000 pieces /mL, >6μm ≤3200 pieces /mL, >14μm ≤400 pieces /mL).
Regularly test the contamination level of the oil. It is recommended to replace the filter element every 200 hours or three months and use offline filtration equipment to maintain cleanliness.
3. Parameter setting and debugging
Basic parameter configuration
Set control parameters through Parker dedicated software (such as Parker IQAN or EtherCAT configuration tools), including:
Signal input range (0-20 mA
Zero point/full-scale calibration of the valve core
Regeneration mode enabled (if necessary).
The pressure compensation function needs to be combined with pressure sensors (such as Parker SCP01 series) for closed-loop regulation to ensure independent flow control of the load.
Regeneration mode operation
The regeneration mode can reduce energy consumption (such as the differential circuit of the hydraulic cylinder), but it should be noted that
Before switching, it is necessary to confirm that the system pressure is stable to avoid shock caused by sudden changes in flow.
The proportion of regenerative flow needs to be adjusted according to the actual working conditions. It is recommended to gradually optimize the parameters through software.
Dynamic response adjustment
If the system experiences oscillation or overshoot, it can be optimized through the following methods:
Increase the Damping Factor of the amplifier.
Reduce the Proportional Gain, but it is necessary to balance the response speed and stability.
4. Operation monitoring and maintenance
Real-time diagnosis
Monitor the following status via the EtherCAT interface or LED indicator lights:
Valve core position deviation (within ±0.5% is normal).
Oil temperature and pressure over-limit alarm (such as oil temperature > 60℃, pressure > 350 bar).
Coil temperature (maximum allowable 100℃) and fault codes (such as short circuit, open circuit).
Regularly record diagnostic data, establish trend analysis models, and predict potential faults in advance.
Preventive maintenance
Daily inspection
Visually inspect whether the pipe joints are leaking oil and whether the electrical connections are loose.
Use an infrared thermometer to detect the temperature of the valve body to ensure there is no local overheating.
Regular maintenance
Clean the external dust every 500 hours and check the wear on the valve core surface (an endoscope can be used for observation).
Replace the seals (such as O-rings and dust rings) every 2,000 hours and clean the internal oil circuit of the pilot valve.
Oil replacement
Change the oil after the first 500 hours of operation, and then every 2,000 hours or based on the results of the contamination test.
