Parking brake valve (71) (From Machine S/No.51200552 only) The parking brake valve is fitted between the hydraulic tank (1), the cooling fan motor (7) and the fan reverse valve circuit (72). The valve is solenoid operated from a switch in the operators cab and applies the parking brake. The valve is supplied with hydraulic fluid from the fan reverse valve (72) and has a solenoid operated valve and a pressure relief valve. When selected by the operator, the solenoid valve operates to supply hydraulic fluid to the parking brake actuators on the front axle. When de-selected, the valve releases the hydraulic fluid pressure to the parking brake and returns the fluid flow to the hydraulic tank (1). Specifications Pressure relief valve Solenoid voltage
18 bar (261 psi) max 12V DC
