One of the key performance factors in any machine is how well the load is controlled. Five spool congurations are available. They allow fluid flow into different paths from one or more sources. In a hydraulic system, flow control valves are used to regulate the flow between motors and cylinders, which in turn manages the speed of those components. Since they also control the rate of energy transfer at any specified pressure, control valves also have a tremendous influence over the total amount of work being done. Atos is a leading international manufacturer of oil- hydraulic solenoid valves . They permit the flow of liquids into distinct routes from 1 or more additional sources. This example engineering drawing showing the directional control valve usage with fixed volume pump and hydraulic cylinder is redesigned using the ConceptDraw PRO diagramming and vector drawing software from Wikimedia Commons file: DCV 19.jpg. The spool slides to different positions in the housing, and intersecting grooves and channels route the fluid based on the spool's position. Directional control valve. Most of the lands often block oil flow that flow through the body of the valve. They can be operated either manually or electronically (solenoid-operated). Hydraulic lines power the valve, which then controls the tilt and horizontal movement of the load table. Sealed and rugged execution with cushioning effect above cetop 05 size.
