Abstract
A solenoid operated hydraulic valve for supplying a regulated hydraulic pressure to a load in dependence upon an electrical demand signal applied to the valve. The valve is operable to sense the temperature of the hydraulic fluid flowing through the valve and to determine the current applied to the valve solenoid in dependence upon both the demand signal from a sensor and the sensed temperature such that the regulated pressure supplied to the load is dependent only on the demand signal and is substantially independent of the temperature of the hydraulic fluid.
