PVCM Series Proportional Pressure Compensated Flow Control Valves

Product Overview:

The PVCM Series is a high-precision cartridge component designed for sophisticated speed regulation in hydraulic systems. As an electro-proportional, pressure-compensated flow control valve, the PVCM maintains a constant output flow regardless of fluctuations in load or system pressure. By integrating advanced electromagnetic proportional technology with internal compensation mechanisms, it is widely utilized in excavator traction, crane swing systems, and precision actuators in automated production lines.

Featured models include: PVCMCFCN1, PVCMCMCN1, PVCMAMCN1, PVCMAFCN1, and the high-performance PVCMAFCN145.

Key Technical Advantages:

• Full Pressure Compensation: The integrated compensator ensures flow is dictated solely by the electrical input signal, shielding the output from pump or load pressure variations.

• Superior Linear Modulation: Precisely calibrated electromagnetic force ensures high synchronicity between input current and flow output, enabling delicate inching maneuvers.

• Low Hysteresis & Rapid Response: Friction-optimized spool designs significantly reduce operational hysteresis, providing instantaneous feedback and control.

• Compact Cartridge Format: Fits standard T-13A or T-16A cavities, allowing seamless integration into custom hydraulic manifolds while reducing plumbing complexity.
