Abstract

A control valve having a pair of service passages for connection with the opposite sides of a reversible fluid motor, wherein a flow control valve for each service passage restricts exhaust flow therethrough to prevent the pressure thereof from exceeding a predetermined value, but in no way influences flow to a fluid motor of supply pressure fluid from its service passage. Flow coordinating means limits flow of supply fluid to each service passage substantially in correspondence with restricted flow of motor exhaust fluid in the other service passage.
