Предохранительный клапан ручного насоса Caterpillar 5627651

The Hand Pump Relief Valve regulates pressure in a manual hydraulic circuit by allowing excess pressure to escape when preset limits are reached, helping maintain controlled operation. It prevents pressure buildup that can cause unstable performance during pumping tasks. Pressure regulation through this valve supports smooth fluid movement and predictable response from connected hydraulic functions. Controlled pressure release helps reduce sudden force changes that may affect operation accuracy.Attributes:• Regulates hydraulic pressure during manual pumping operations.• Releases excess pressure to maintain controlled fluid movement.• Supports stable hydraulic response under varying force input.Applications:The Hand Pump Relief Valve is installed in the hand pump line of the hammer group to control maximum pressure, prevent overpressure, and ensure safe, reliable operation during manual pumping.
