PVCMCMCN3 PVCMCM1N1 PVCMCKV3 PVCMCKV8 Parker Pressure Control Valve 350 bar

Product Overview

The PVCM series pressure control valves are dedicated pressure control components engineered by Parker Hannifin for the PV series axial piston pumps. These valves mount directly on top of PV series piston pumps to precisely regulate pump output pressure, ensuring stable and reliable pressure supply to hydraulic systems under all operating conditions. When the valve is damaged, it can be replaced with the same model without replacing the entire pump—significantly reducing maintenance costs.

The PVCM series covers models including PVCMCKV3, PVCMCKV8, PVCMCLZN1, PVCMCMCN1, PVCMCMCN3, and PVCMCM1N1. The series is compatible with Parker PV series piston pumps with displacements ranging from 16 to 360cc. Valve bodies are manufactured from high-strength materials with optimized internal flow paths, offering high precision, wear resistance, and contamination tolerance.

Our complete range of Parker PVCM pressure control valves strictly adheres to OEM technical standards, achieving 100% direct interchangeability with original components. Every unit undergoes 100% simulated operating condition bench testing prior to shipment, ensuring performance parameters are fully consistent with genuine Parker products. Direct replacement significantly reduces equipment downtime and maintenance costs.

Key Technical Advantages

1. Precise Pressure Control for PV Series Piston Pumps

The PVCM series pressure control valves are specifically designed for Parker PV series axial piston pumps, precisely regulating pump inlet pressure to the required outlet pressure. The valve relies on the medium’s own energy to automatically maintain constant outlet pressure within a specified tolerance. Compensator pressure is continuously adjustable within the 15 to 350 bar range.

2. High Precision, Wear Resistance, and Contamination Tolerance

PVCM series spools are manufactured from specialized materials with hardness up to HRC60 or above, providing superior wear resistance and significantly extended service life compared to conventional control valve spools. Valve bodies are constructed from cast steel, offering high precision, wear resistance, and contamination tolerance—ensuring reliable performance even under harsh operating conditions.

3. Modular Compensator Design with Fast Response

The PVCM series features a modular compensator design with fast response characteristics. FEM-optimized housings and pre-compression chambers effectively reduce output pulsation and noise. Full-power through-drive capability and low power consumption design enable more efficient system operation.

4. Compact Design with Direct Pump-Mounted Installation

PVCM series control valves mount directly on top of PV series piston pumps—requiring no additional piping or mounting brackets, greatly simplifying system integration. The compact design delivers high-performance pressure control within limited installation space.

5. Broad Displacement Compatibility

The PVCM series is compatible with Parker PV series piston pumps with displacements ranging from 16 to 360cc. Whether PV016, PV032, PV046, PV076, PV092, PV140, PV180, or PV270 displacement variants, the corresponding PVCM control valve can be selected for precise pressure control.

6. 100% Direct Interchangeability and Simulated Condition Testing

All models strictly adhere to Parker original mounting dimensions and interface standards, enabling direct drop-in replacement of original control valves without pump modification or system adjustment. Every unit undergoes 100% simulated operating condition bench testing prior to shipment, ensuring consistent, stable performance at rated pressure.

Expert Maintenance Tips

1. Verify Model and Pump Compatibility Prior to Installation

PVCM series control valves are compatible with different displacement PV series pumps. Confirm that the control valve model matches the pump displacement—for example, PVCMAMCN1 is primarily suitable for PV032-046 pumps. Mismatched models will result in abnormal control characteristics and significantly impair system performance.

2. Pressure Setting and Commissioning

PVCM series control valves offer compensator pressure adjustment within the 15 to 350 bar range. To adjust: first loosen the lock nut (SW 13), then rotate the adjustment spindle using a screwdriver. Retighten the lock nut after adjustment is complete.

3. System Cleanliness Management

PVCM series control valves feature precision internal clearances and demand adequate oil cleanliness. Recommended system cleanliness: ISO 4406 Code 18/16/13 or higher. Thoroughly flush system piping prior to installation. If spool sticking occurs, disassemble the valve body following the Parker manual sequence and flush the spool, sleeve, and valve body cavity with acetone or specialized hydraulic cleaner.

4. Installation Torque and Sealing

PVCM series control valves mount directly on top of PV series piston pumps. Use a torque wrench to tighten mounting bolts to the values specified in Parker technical manuals. Use OEM-specification O-rings for sealing—inspect seal condition prior to installation and replace if worn or damaged.

5. Periodic Functional Checks

Perform functional checks every 2,000 operating hours or annually to verify pressure regulation accuracy and response characteristics. If abnormal pressure fluctuation, sluggish response, or set pressure drift is observed, arrange for servicing or replacement.
