Product Description
Hydraulic Pressure Reducing Valve & Relief Valve 723-50-61200 / 723-50-62300 (Fikowjs Compatible for Komatsu PC130-8/PC138US-8)
The Fikowjs 723-50-61200 and 723-50-62300 are high-performance hydraulic pressure control valves designed as direct replacements for Komatsu PC130-8 and PC138US-8 excavators. These valves work in tandem to regulate hydraulic system pressure: the pressure reducing valve maintains consistent downstream pressure for auxiliary functions, while the relief valve protects critical components by diverting excess pressure to the tank, preventing overloads and potential damage.
Key Features:Precision Pressure Regulation:
The reducing valve ensures stable secondary pressure for precise control of hydraulic actuators, enabling smooth operation in tasks requiring fine movements (e.g., grading, lifting).
The relief valve activates at 34.8 MPa (main circuit) or 27.1 MPa (swing circuit), aligning with Komatsu’s original specifications to safeguard pumps, cylinders, and motors from pressure spikes.
Robust Construction:
Manufactured from hardened steel and equipped with NBR seals for compatibility with hydraulic oils, ensuring durability in harsh environments (temperatures: -20°C to 120°C).
Komatsu-Specific Compatibility:
Engineered to match the hydraulic configurations of Komatsu PC130-8 and PC138US-8 models, including integration with swing gearboxes and pilot control systems.
Direct bolt-on replacement with identical port sizes (e.g., G1/4" or G3/8" BSPP threads) and mounting specifications, simplifying installation.
Enhanced Safety and Efficiency:
Prevents system overheating and energy waste by minimizing pressure creep and unnecessary fluid bypass.
Reduces downtime by protecting hydraulic components from failures caused by overpressure.
Model Numbers: 723-50-61200 (Pressure Reducing Valve), 723-50-62300 (Relief Valve)
Compatible Models: Komatsu PC130-8, PC138US-8, and similar-series excavators.
Pressure Ratings:
Relief Valve Setting: 34.8 MPa (main circuit)
Reducing Valve Output: Adjustable range (e.g., 5–35 MPa, model-dependent)
Flow Capacity: Up to 150 L/min (reducing valve)
Seal Material: Standard NBR (Buna-N) for hydraulic oil resistance
Excavator Hydraulic Systems: Protects and regulates pressure for boom, swing, and travel circuits.
Auxiliary Equipment: Ensures safe pressure levels for attachments like breakers or grapples.
These valves replicate OEM performance at a competitive price, offering reliability and compliance with Komatsu’s engineering standards. Their design minimizes maintenance needs and extends the lifespan of hydraulic systems in demanding construction environments.
