You can use the command pgrep, where also the switch -w can be used:

pgrep -w "rv"

The final result is the process ID of the rv process.

Just append the -w argument to grep

ps -af | grep -w rv

ps -af | grep -w rv

ps -af | grep --word-regexp rv

You can use

ps -af | grep -w "rv"

Alternatively, you could match the term using regex
