Abstract:
The present disclosure relates to a hydraulic valve that has a two-stage con-struction that provides for higher fluid flow and lower power consumption. The present disclosure also relates to a hydraulic valve that may be constructed to include a pilot-poppet, a pilot-poppet valve seat, and a main-poppet. The main-poppet may be mechanically isolated from the pilot-poppet by the pilot-poppet valve seat.
