This valve serves to control \/ controlling the size of the hydraulic fluid flow .It is assumed that the magnitude of the flow is the amount of hydraulic fluid flowing volume will affect the speed of movement of the actuator.<\/span> Various flow control:<\/span> The basic construction of the flow control there are two kinds:<\/span><\/p>\n Table ristrictor various forms and characteristics.<\/span> Valve One Way<\/strong><\/span>
\n a.<\/span> Fix flow control passageways size of the hole is fixed (not adjustable)<\/span>

\n This valve serves to regulate fluid flow only in one direction only, namely when the fluid has passed through the valve so the fluid can not be reversed.<\/span> Various valves unidirectional:<\/span>
