A proportional seat valve with a mechanical position feedback slot has the capabilities of a wide range of flow rate control and quick-response control for fluid power systems. However, it is unstable in the case of rotational speed control of a hydraulic motor with an inertia load. The reasons for this is that the valve works sensitively against the load pressure changes. This paper presents an improved seat valve with a balance spool and shows the stabilized dynamic characteristics. The valve controls flow rates of 70 L/min at pressure difference of 10MPa within 20ms by PWM switching pilot valve. Furthermore, it is shown that a set of computer-controlled 4-seat valves will offer freedom of pressure or flow rate control to a conventional full bridge hydraulic circuit.
