Abstract
Dynamic operatin limit of a directional valve is determined with the maximum pressure and maximum through-flow which is still allowed not to interfere a reliable operation. When a directional valve is operated at limit values (i. e. maximum pressure and through-flow) diferent interfering forces are effective on the valve spool. These can exceed the actuating forces which are available from the control solenoid and return springs. By means of mathematical modeling and comparation analyses there is necessary to find optimal shape of direction valve which allows a reliable operation at limit pressure and through-flow values.
