CQJ-25	25		NXQ-*/20	P=25		D8×2		1.7
CQJ-40	40		NXQ-*/31.5	P=40		D8×3		1.7

1.the charging and testing units are designed to charge,test gas pressure of nitrogen  and the existed pre-charge pressure.

2.when the max pressure of accumulator charged is less than max pressure of nitrogen cylinder,relief valve is used to charge the accumulator.

3.note:after charging,the connector between nitrogen cylinder and accumulator should be closed,and then open the bleed valve of charging tool to exhaust completely the gas in hose,finally,unload the charging tool.
