4-way sectional directional control valve type 4/3 UREM6 up to 35/21 MPa up to 50 dm3/min NS6 DAT RAT MANUA UAL DATA SHEET - OPERATION MANUAL APPLICATION Electrically operated 4-way sectional directional control valve type 4/3UREM is intended for changing 4/3UREM… hydraulic fluid flow in a hydraulic system, which enables change of direction of the receiver’s movement, usually the cylinder piston rod or a hydraulic motor, and performance of modes: start / stop. It is designated for layer mounting in a block, in any position in a hydraulic system, it is intended for mobile applications. left side of subplate (main stream) right side of subplate (residual stream – bypass) 4-way sectional directional control valve type 4/3UREM6… is mounted in layer system in block 4/3UREM6 assembled with max. 8 sections on one side of the inlet port. Port P and T can be located in the inlet cover (1), which can be equipped with a relief valve (3) or a relief valve (3) and unloading directional valve (4). Ports P and T can be also located in the inlet, middle plate (2) equipped with a relief valve (3) and 3-way flow regulator (5) electrically, proportionally operated (or manually adjusted).

Each of the sections of the valve is available in a version allowing for transmission of voltage from the previous to the next section by a parallel connection of channels (versions R…; ZR ZR…), or serial (version S…). Each of the sections has ports A and B for connection of receiver (for example: hydraulic cylinder). Single section of directional valve electromagnetically operated consists of body (1), spool (2), solenoid (3), with manual override button (4) and reverse spring (5). In case of lack of power supply, shift of spool can be made by manual override button (4). Additionally single...
