This paper introduces a pilot operated miniature digital hydraulic valve with a high flow capacity, in comparison to the size of the valve, and a fast response. The valve is designed to be used as a part of a digital valve system, which consists of a large number of similar valves. This paper presents the structure of the valve as well as the response time, flow capacity and leakage measurements of the prototype. The presented valve has a volume of approximately 4 cm3 and a flow capacity of 9 l/min with a 3.5 MPa pressure difference. Its response time is approximately 1 ms and the maximum operating pressure exceeds 30 MPa.
