RP70-1523 hydraulic valve
Classification:
Product Description
Overview
The RP70-1523 valve body is designed to change the flow direction and perform the functions of "lifting", and "fixing the hinge in a given position", as well as automatically adjusting the depth of travel in the hydraulic system of tractors, agriculture, road machinery and other equipment. The distinctive feature of the RP1523-70 valve body in the distributor series of type RP70 is the presence of the electro-hydraulic regulator ENRNS1 manufactured by ARGO-HYTOS of the Czech Republic, which is installed in the RP79-1221 distributor instead of the RP70-012 drain cover. The electro-hydraulic regulator ENRNS1 provides the functions of "lifting", "" and "fixing the attachment in a given position", as well as automatic adjustment of the stroke depth of the farm implement when working with the electronic heddle of the company BOSCH or the electronic heddle of the factory IZMERITEL.
