Directional control valves (DCVs) are one of the most fundamental parts of hydraulic and pneumatic systems. DCVs allow fluid flow (hydraulic oil, water or air) into different paths from one or more sources. DCVs will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. The position of the spool restricts or permits flow, thus it controls the fluid flow.
The spool (sliding type) consists of lands and grooves. The lands block oil flow through the valve body. The grooves allow oil or gas to flow around the spool and through the valve body. There are two fundamental positions of directional control valve namely normal position where valve returns on removal of actuating force and other is working position which is position of a valve when actuating force is applied. There is another class of valves with 3 or more positions that can be spring centered with 2 working position and a normal position.

 Metal SeparatorApplication:
Metal separator is used for the detection of industrial products of iron, stainless steel, copper, aluminum and all other metal impurities, such as in the food, plastics, pharmaceutical products production process,it's easy to mix metal impurities, not only affect the quality of products, also do a lot of harm to consumers.
During the plastic molding process, thin metals inside the raw materials always present invisible hidden hazards to our molding equipment, for example, screws of molding machines are abnormally worn and torn and nozzles are blocked, etc. Most of those hazards are caused by metals existing in the raw materials. HADRDEGA also has perfect solution for hazards of that field
