SLIDING SPOOL VALVES The sliding-spool valves are the most frequently used type in hydraulic systems. Fig.6.2 illustrate a typical sliding spool valve. A spool moves horizontally within the valve body to control the flow. The raised areas called 'lands' block or open port to give the required operation. In Fig.6.2(a), the fluid supply is connected to port 1 and now port 3 is in closed position. Thus the flow is permitted from port 1 to port 2. In Fig.6.2(b), when the spool is moved to the left, the fluid supply is cut off and port 2 is connected to port 3. Thus the flow is permitted from port 2 to port 3. (i) Different operations can be achieved with a common body and different spool. (ii) Reduced manufacturing cost. (iii) Reduced fluid leakage rate. (iv) All types of actuation are easily adaptable. They are used for high pressure applications.1. Construction and Operation
