Question: 1 / 400

What is the role of hydraulic check valves in circuit design?

To increase the system's overall pressure

To maintain pressure in certain sections of the circuit while allowing flow in selected directions

Hydraulic check valves play a crucial role in circuit design by allowing fluid to flow in one direction while preventing backflow. This function is essential for maintaining pressure in specific sections of the hydraulic system, ensuring that components receive the necessary pressurized fluid for proper operation. By enabling flow in selected directions, check valves help to control the sequence of operations within a hydraulic circuit and protect sensitive equipment from damaging reverse flow.

In multiple hydraulic circuits, maintaining pressure in particular areas can be vital for effective system performance, especially in applications involving actuators, where it’s essential to hold load positions without using external energy sources. Therefore, the primary purpose of a check valve aligns perfectly with the need to sustain pressure and direct flow appropriately in hydraulic systems.
