Advantages and features of Parker directional control valves

‌High dynamic response and repeatability‌

With high frequency response characteristics (-3 dB / 350Hz), it is suitable for scenarios with high precision and high cycle requirements (such as servo control or precision machine tools);

Low hysteresis and improved process give excellent repeatability, ensuring operational stability and consistency, and improving production process accuracy.

‌Diverse structural design and adaptability‌

Support direct-acting (D9P series) and pilot-operated (D91FCE series) control, rich valve core options (such as zero-turn spool, overlapping valve core), adapt to different flow and pressure requirements;

Compact modular design (such as D3W series) achieves low pressure drop (reduces energy loss) and high flow performance, taking into account space constraints and efficiency requirements.

‌Intelligent integration and compatibility‌

Built-in digital electronic equipment (such as D3FP series), supports free parameter configuration and remote monitoring, and is easy to integrate with PLC or industrial automation systems;

The valve core can be positioned when the power is off (optional P-A/B-T or center position) to avoid the risk of system loss of control.

‌Economical efficiency and maintenance convenience‌

Short delivery cycle (no warehousing required) and cost-effective design reduce procurement and inventory costs;

Core components are made of wear-resistant materials (such as alloy valve core), with long maintenance cycle, supporting quick replacement of seals and manual emergency operation.

Precautions for the use of Parker directional control valves

‌Installation and commissioning specifications‌

Before installation, ensure that the oil cleanliness meets the NAS 1638 standard (recommended level 7-9), and configure a 10μm filter in the pipeline to prevent particles from wearing the valve core;

Calibrate the coaxiality of the valve body and the actuator to avoid seal failure or valve core jamming caused by eccentric load.

‌Operational restrictions and monitoring‌

Prohibit overpressure operation (the rated pressure of direct-acting valves refers to the specific model, and the pilot valve must ensure the minimum pilot pressure);

Regularly monitor the oil temperature (≤65℃) and vibration signals, and abnormal noise or response delays require immediate shutdown and investigation.

‌Maintenance and special working conditions‌

Check seal wear every 500 hours, replace hydraulic oil every 2000 hours, and give priority to original accessories during maintenance;

When starting in a cold environment, the oil needs to be preheated to above 15°C. In high-frequency switching scenarios, it is recommended to install a buffer valve or accumulator to reduce impact.

‌System integration optimization suggestions‌

When integrating digital amplifiers (such as PCD00A-400), it is necessary to verify signal matching to avoid electromagnetic coil overload or command conflict;

Complex faults are preferentially diagnosed remotely by authorized service providers, and non-professionals are prohibited from disassembling valve blocks or adjusting parameters.
