DF20 Multi-way valve,which is characteristic of compact structure,no escape and universal,etc.,is a kind of multiple directional control valve of layer structure,with each reversing coupler being able to freely rearrange and combine,being very flexble.As oil circuit connection form between each reversing coupler is multiple circuits,relief valve of oil inlet and safely under the highest working pressure.This multi-way directional valves is mainly used for hydraulic system,such as petroleum machinery,hoisting machinery,and mining machinery,etc.,and can centralized control multiple mechanisms.
This valve is mainly composed of three parts,including oil inlet body,reversing coupler body and oil return body.Thereof,Oil inlet does not have the two oil inlet P and P1 that is available for users to choose,and reversing coupler has multi sliding valve functions.There are two locaton forms for the valve core,including steel ball positioning and spring return,which can meet the requirements of different working conditons.To prevent oil in the working cavity back flowing to P cavity,one-way valve is installed inside each reversing coupler,so that nod phenomenon of executive components can be over-come.There are two types of return oil valve body,one is standard oil return body,functioning as leading oil directly into the tank ;the other is bridge oil return body,playing the role of leading oil into the next hydraulic device when reversing valve is in a neutral position.
