Pressure builds up in a hydraulic valve due to resistance to flow and force exerted by the pump.

• Hydraulic valves control the flow of fluid in a hydraulic system.

• When the valve is closed, the fluid is blocked and pressure builds up behind the valve.

• The pressure builds up due to resistance to flow and force exerted by the pump.

• When the valve is opened, the fluid flows through the valve and the pressure drops.

• The pressure...read more
