Abstract
A load sensing electric-proportional multi-way valve. The technical problem to be solved by the present application is to provide a load sensing electric-proportional multi-way valve, enabling individual loops to operate with different loads, to save energy and reduce the environmental pollution. The technical solution for solving the technical issue includes as follows. A load sensing electric-proportional multi-way valve includes a main oil passage connected with two gear pumps P1 and P2, a lifting loop connecting to the main oil passage via an electric-proportional pressure compensated flow control valve, and an inclining union and an attachment union connecting to the main oil passage via an electric-proportional pressure compensated flow control valve, a logic direction valve connected to the main oil passage, a proportional motor-driven overflow valve and a two-way solenoid valve connecting to an oil inlet port of the logic direction valve.
