What if I use an open center tool on a closed center system or vice-versa?
Closed center tools on open center systems will stop oil flow entirely when not in use. Full system flow will then be forced through the system relief valve. No damage; but some noise and the oil will heat rapidly. Open center tools on closed center systems will not stop oil flow and the system will continue to pump oil. No damage; but the advantages of the c.c. system will be negated.
