13. Valve Enclosures

Figure 15

When you see an enclosure outline, (Fig 15) that

indicates that there are several symbols that make

up a component assembly such as a valve body or

valve stack. The enclosure outline appears like a

box and is broken with dashes on all sides.

14. Complete hydraulic schematic

Figure 16

Here we have a simple hydraulic schematic (Fig

16) using the symbols that we discussed and how

they are used in a complete schematic. You can

see that we have a hydraulic pump which gets it’s

fluid from the reservoir, pulls the fluid through the

filter than sends it to the valve. The valve directs

the oil to the hydraulic cylinder.
