Abstract
A valve includes a valve housing () for transport of a heatable fluid such as hydraulic oil. The valve housing has at least one utility connection (A, B), at least one pressure supply connection (P), and at least one return connection (T, T). A control slide () is guided in the valve housing () in a longitudinally displaceable manner. In at least one position of the control slide (), the pressure supply connection (P) is at least partially separated from the utility connection (A, B), and the heatable fluid arrives, proceeding from this pressure supply connection (P) and via a heat-emitting connection in the control slide (), at the at least one return connection (TI, T) as a loss volume flow. The loss volume flow serves as a heat source and heats at least regions of the control slide ().
