Static characteristics of a new type poppet valve which has series restriction chokes are studied analytically and experimentally. It has been definitely shown that the valve has the valuable characteristic for a proportional control, that is, the lift of the poppet and the total flow rate are proportional to the opening of a pilot valve. The influence of the load pressure on the flow rate can be reduced by the newly presented "Area Compensation Method". The new type poppet valve is available for a proportionally and remotely controllable element in a hydraulic system.
