ABSTRACT:
A plurality of pilot valve controlled coolant control valves are mounted in manifolds which in turn are positioned adjacent the work and backup rolls of a rolling mill and used to supply coolant to said rolls in desirable spray patterns covering the surfaces of the rolls. The control valves are operable by fluid pressure of the coolant so as to fail-safe in open position to continue delivering coolant to the rolls to protect the same during an unscheduled interruption.
