Parker TPCC Flow Control Valve Unit

Module Feature

TPCC-600-S-6-02LR belongs to Parker Manatrol TPC series compensated flow control valve. It adopts combined temperature and pressure compensation design, automatically offsets flow fluctuation caused by hydraulic oil viscosity change and system pressure variation. Integral one-way check valve allows free reverse flow for return path. Manual adjustable flow setting, stable flow output, low minimum differential pressure requirement. Inline threaded installation structure, compact body. Widely used in machine tool, material handling, press and industrial hydraulic speed regulation circuits.

Working principle

When fluid flows forward, the compensator spool adjusts throttling opening dynamically to keep volumetric flow stable regardless of inlet pressure and oil temperature. Reverse flow opens the built-in check valve directly without throttling restriction. The needle screw sets the target flow rate manually. The compensation mechanism continuously balances pressure drop and viscosity drift to hold consistent actuator speed.

Onboard componentsAdjustable needle throttling assembly, pressure & temperature compensator spool, reverse flow check valve, valve body, setting knob, seal package.

LED indicatorsNo onboard LED indicators. Flow condition is judged by actuator speed and external pressure gauge.

Hardware self-diagnosisExternal pressure differential monitoring, actuator speed stability inspection, external leakage check, contamination inspection of spool assembly.

Programming softwareNo configuration software, flow rate set mechanically by adjustment knob.

EnvironmentalOperating temperature:-20℃ ~ +80℃ Storage temperature:-40℃ ~ +85℃ Ambient humidity:5~95% non-condensing Certification:Industrial hydraulic compliant Status: Parker original TPC series flow control valve

InstallationDepressurize hydraulic circuit before installation. Install Parker TPCC-600-S-6-02LR inline valve following marked flow direction. Connect inlet and outlet hydraulic piping. Adjust flow knob to set target actuator speed, verify speed stability under varying load pressure.

InterfaceThreaded inlet port, threaded outlet port, manual flow adjustment knob.

DiagnosticSpeed drifts under changing load: insufficient differential pressure for compensator operation or contaminated spool. No reverse flow: check valve stuck closed. External leakage: worn seal ring assembly.
