DR4 Reversing Valve
The DR4 Reversing Valve alternates the flow of lubricant thru the lines of Dual Line systems so that lubricant is directed first to one supply line then the other, during system cycles. The reversing action is automatic, controlled hydraulically by the action of a pressure sensing mechanism within the valve.
Model DR4-5 reversing valves supersedes the DR10, DR2, DR4-1, DR4-2, DR4-3, and DR4-4 reversing valves.
DR4-5 valves are available for both return and non-return systems with adjustable pressure range as indicated below.
