1 way section directional valve type URRE NS up to 5 Ma up to 80 D SHEE SERVICE MNU NUL dm /min WK LICION way section directional valves type URRE are used to change direction of fluid flow in hydraulic system and thus it allows change direction of movement of a receiver (mostly piston rod or hydraulic motor) and also to use two functions: on and off. hey are also used to set pressure independently in ports (cavities) and and to set maximum pressure in a system. hese directional valves allow for free oil drain to a tank via additional port when the system is unloaded in neutral position of directional valve. he directional valves are intended for threaded mounting in any position in hydraulic systems. DESCRIION OF OERION way section directional valves type URRE consist of the following main controls: flow direction control section and covers. Sections with various types of adjustment versions shown in the picture: hand lever () operated and electrohydraulically () operated are sandwichmounted versions. hey are closed outside with supply cover () and outlet cover (). In sections () and () are cavities which serve to be connected to receivers (hydraulic cylinders). Sections () and () may be equipped with pressure relief valves (5) nominal size (NS) type UZS according to data sheet WK 0 0 used to set pressure separately in ports (cavities) and or check valves type UZZD according to data sheet WK Covers () and () include suitably located supply port and outlet (drain) port. In supply cover () is mounted pressure relief valve () type UZS according to data sheet WK 9 80 used to set maximum pressure in a system. In outlet (drain) cover (), however, there is mounted pressure relief valve (7) type UZMD according to data sheet WK which is used to maintain pressure only for electrohydraulically operated version URRE / EH EH).

Due to heating solenoid coils, directional valves with protective earth wire ( E ) in supply should be placed in order to eliminate the system according to appropriate instructions. possibility of incidental touch while using, or,. It is forbidden to apply directional valve if the supply cable in the gland of plugin inconnector is not properly tightened. they should be equipped with the coil covers (in accordance with the European standards N EN ISO 7 and N EN 98).
