A valve for controlling the flow of hydraulic fluid to a hydraulic motor. The valve includes a sleeve and a spool. The sleeve includes a first fluid flow port for receiving hydraulic fluid from the supply line; a second fluid flow port for supplying hydraulic fluid to a second valve; a third fluid flow port for receiving hydraulic fluid from a first control line; a fourth fluid flow port for receiving hydraulic fluid from a second control line; and a fifth fluid flow port in fluid communication with the return line. The valve is arranged to be actuated to move the spool between a first position and a second position. When the spool is in the second position, the fifth fluid flow port is in fluid communication with the second, third and fourth fluid flow ports and the first fluid flow port is closed by the spool.
