ROTARY SPOOL VALVES Rotary spool valves have a rotating spool which aligns with holes in the valve casing to give the required operation. Fig.6.3 illustrates the construction and operation of a typical rotary spool valve, with centre off action. When the spool rotates, it opens and closes ports and subsequently allows and prevents the fluid flow through that ports. In Fig.6.3, there are four ports 1, 2, 3, and 4. For the position of spool as in Fig.6.3(a), the flow is permitted from port 1 to port 3, and from port 2 to port 4. When the spool rotates to a position as shown in Fig.6.3(b), the flow is permitted from port 1 to port 4, and from port 2 to port 3. For the spool position shown in Fig.6.3(c), there is no fluid flow as all the four ports are blocked. (i) They are simple and compact in design and operation. (ii) They have low operating forces. The rotary spool valves are widely used for low pressure applications.1. Construction and Operation
