Cam characteristics:

Linear (cam 1, standard) and two other kinds. By selecting the other two cams, valve characteristics can be approximated as follows:

(1) For reverse acting valve

Cam 2

• Linear characteristic valve plug

--> Quick opening characteristic

• Equal percentage characteristic valve plug

--> Linear characteristic

Cam 3

• Linear characteristic valve plug

--> Equal percentage characteristic

• Quick opening valve plug

-->Linear characteristic

(2) For direct acting valve

The effect of cams 2 and 3 applied to direct action valves is reversed as compared with the case of reverse action valves.
