Предохранительный клапан поршневого насоса Caterpillar 2041458

The Piston Pump Relief Valve controls and limits the maximum hydraulic pressure generated by the piston pump. It opens to release excess pressure when hydraulic load exceeds preset limits, preventing damage to the pump and connected components. The valve ensures stable pressure levels, allowing smooth and safe operation of hydraulic circuits.Attributes:• Balances pressure between connected hydraulic lines.• Automatically opens to relieve excess pressure in hydraulic pump circuits.• Minimizes shock loads and prevents pump and actuator damage.Applications: The Piston Pump Relief Valve is positioned in the piston pump circuit, where it regulates excess pressure and provides crossover balancing, ensuring smooth hydraulic operation and preventing component damage during load variations.
