Retrofitting from breaker piping to grab piping :

When retrofitting the breaker piping lines to grab piping lines, take the return line of the existing
breaker piping lines for the grab closing lines of the grab. If the return line of the existing breaker
lines is also installed for low pressure only, we recommend you to replace all the piping lines with
the adequate piping lines as required above and make the lines both supply and return lines to high
pressure lines. If the breaker supply line is taken for the grab opening line, relief valve on the
breaker supply line does not need to be reset. (But the setting pressure must be more than 230
bar)
