Reverse valve Reverse directional valve type URJP10... is used for continuous duty together with a hydraulic cylinder. It functions in self-reversible cycle. It is applied in scraping systems e.g. dung or sawdust. The reverse directional valve can operate under fire hazard The reverse directional valve type URJP10... makes an automatic change in direction of fluid How. It is possible by opening and closing the How lines by means of a working element - a spool in this case. The reverse directional valve type URJP10... is 4-way 2-position directional spool valve automatically controlled. The piston rod of a cylinder reaches the extreme position causing increase of the pressure in a system up to the set pressure at pressure relief valve and at the same time causing decrease of How rate. In this moment the reverse directional valve is switched automatically and the direction of movement of the piston rod is changed. Minimum pressure set at pressure relief valve in the hydraulic system should be 2 MPa in order to secure the shift of the spool. The pressure as the result of loading outside cylinder should be lower by at least 0,6 MPa than the pressure set at pressure relief valve. It is recommended that the reverse directional valve. The reverse directional vale is recommended to work together with a cylinder of minimum piston diameter 63mm.
