Parker PV Series Pump Regulator | PVCPEHS1N1 PVACPPDSV42 PVACBLTMN20

LIC Hydraulic proudly offers the Parker PVCP and PVAC Series pump regulators and proportional valves. These control blocks are the high-precision “intelligence” behind Parker’s PV series axial piston pumps (PV016 to PV270). Featuring advanced models like PVCPEHS1N1 and PVACPPDSV42, these regulators enable electro-hydraulic control of displacement, pressure, and power. Whether you are building a closed-loop CNC system or a heavy-duty industrial press, Parker regulators provide the millisecond response times and accuracy required for modern high-performance hydraulics.

Technical Specifications (Quick Reference)

• Control Types: Proportional Displacement (PVCP), Remote Pressure Control (PVAC), and Power Limiting.

• Compatibility: Direct mount for Parker PV063, PV080, PV092, PV140, PV180, and PV270.

• Operating Voltage: Typically $24\text{V DC}$ for proportional solenoids.

• Hysteresis: Ultra-low, typically $<3\%$, ensuring extreme repeatability in precision manufacturing.

Key Technical Advantages

• Rapid Dynamic Response: The pilot-operated design ensures the pump’s swashplate reacts instantly to electronic command changes, minimizing hydraulic shock.

• Integrated Solutions: Combining multiple functions (like pressure compensation and power limiting) into a single block simplifies system architecture and reduces potential leak points.

• Electronic Feedback Options: Models like the PVCPEHS1N1 can be equipped with LVDT sensors for the highest level of closed-loop positioning accuracy.

• Rugged Construction: Built to withstand the high vibrations and thermal cycles of 24/7 industrial production environments.

Application Areas

• Metal Forming & Stamping: Precision control of ram speed and pressing force.

• Plastics Machinery: Dynamic flow control for injection and clamping cycles.

• Testing Rigs: Providing variable, highly accurate pressure sources for aerospace and automotive testing.

• Heavy Duty HPUs: Used in synchronized lifting or complex material handling systems.

Expert Maintenance Tips

• Dither Settings: Ensure the proportional controller is correctly configured with the recommended dither frequency (usually $100\text{–}160\text{ Hz}$) to minimize friction and hysteresis.

• Zero-Point Calibration: Periodically check the electronic zero-point of the PVCP regulator. Over time, mechanical wear may require a slight offset adjustment in the PLC to maintain perfect accuracy.

• Filtration Standard: Proportional regulators are highly sensitive. A dedicated $10\text{ }\mu\text{m}$ absolute filter on the pump’s pressure line or pilot supply is mandatory to prevent orifice clogging.
