The invention is to provide a modular combined electro-hydraulic multi-way valve system using compact two-way cartridge valves. Two sets of seat valve main stages including two compact two-way cartridge valves separately are used to control two reversible controlled cavities, a cartridge pressure compensation control assembly is used to control load compensation, and valve body forms the main part of electro-hydraulic multi-way valve; The main body has the function of self-supply-oil pilot control by two side flange control plates; The main part of electro-hydraulic multi-way valve, side flange control plates, pilot stages and auxiliaries combine sandwich self-supply-oil high-voltage electro-hydraulic multi-way valve reversing league with four main ports P, T, A, B and multiple control ports Pc, Tc, Ls and auxiliary ports; The system can satisfy the requirements of higher efficiency, energy saving, low emission and diversity raised by equipment manufacturers through more kinds and more reasonable modular combined configurable solutions.

Modular combined electro-hydraulic multi-way valve system using compact two-way cartridge valves

A compact two-way cartridge valve with combined flanged cover includes combined flanged covers, miniaturized pilot control assemblies and main stage of seated poppet valve, or combined flanged covers and main stage of seated poppet valve, or combined covers and miniaturized pilot assemblies and main stage of seated poppet valve. The present invention can overall realign all the two-way cartridge valve products currently on the market, and innovate new series of MINISO compact two-way cartridge valves in the specifications of 10 mm, 16 mm, 25 mm, 32 mm, and will change the quo-status of hydraulic drive and control system, that is the two-way cartridge valves currently are mainly used for large power or flow situations, and can make two-way cartridge valves applied for medium and small power or flow situations, which are the majority of the market in the hydraulic drive and control system.

Compact two-way cartridge valve using combined flange-controlled plate

A combined hydraulic integrated control valve block system includes pilot control valve group, control valve subassembly, combination of valve blocks which are connected with external part for installing the pilot control valve group and the control valve subassembly. The pilot control valve group includes multiple pilot control valves and the standard installation surface for the pilot valve is formed on the valve block. The control valve subassembly includes multiple two-way cartridge valve control subassemblies. The valve block is formed with one or two external installation surfaces, the inner side of which has P, T, A and B main channels and multiple pilot control channels.

Combined hydraulic integrated control valve block system

A combined hydraulic control valve is disclosed, the valve includes a modularized pilot control valve assembly (), a modularized two-way cartridge valve control assembly (), and a valve block body (); the modularized pilot control valve assembly () and the modularized two-way cartridge valve control assembly () are connected to the valve block body () to constitute the combined hydraulic control valve. The pilot control valve assembly () is mounted on the upper mounting surface () of the valve block body (); the two-way cartridge valve control assembly () consists of a valve seat main stage () and a control cover plate () which is assembled at a side of the valve seat main stage (), and the valve block body () has a mounting hole () for inserting the valve seat main stage () of the cartridge valve control assembly ().
