The device redirects or stops the fluid flow with the help of internal mechanism in the valve. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. They are mostly used as link between two consumers and the basic directional valve, With a wide range of actuation plus ATEX, UL and CSA approved explosion-proof options, learn why OEMs the world over rely on Eaton’s DG valves. The movement of the spool restricts or permits the flow, thus it controls the fluid flow." 02 Directional control valve, direct operated WRP 03 With integrated electronics E 04 Size 10 10 05 Symbols e.g. The valve spool get shifted with respect to the valve body which opens or closes valve ports for controlling fluid flow.

C, C1, C5 etc. The symbols are described in the standard ISO 1209. Valve with external trigger electronics 8 and 9 Characteristics curves 10 and 11 Unit dimensions 12 to 14 Features – Pilot operated 4/3-way servo solenoid directional control valves NG10 to NG25 – Pilot valve NG6, with control The only difference between this valve and symbol and those in Figure 10-23 is that the pilot control is a double-solenoid, detented valve instead of having a return spring. Pilot oil pressure is resisted by a spring, which can often be adjusted. 23-1 E Directional Control Valves Functional Symbols 1 Hydraulic fluid Omit: mineral oil based fluid, water-glycol based fluid F3: Phosphate ester 2 Mechanically operated directional control valve (gasket mounting) Mounting ISO 4401 Introduction 5 Ordering code 5 Name "Directional control valves are one of the most fundamental parts in hydraulic machinery as well and pneumatic machinery. Directional valves type KV with direct mechanical operation by means of a lever control the direction of the hydraulic medium flow. These valves have … E, E1-, W6- … EC Declaration of Conformity 4 2. It is particularly suitable for controlling double-action cylinders. Pilot-Operated Relief Valves Hydraulic Circuits A pilot-operated relief valve can be used to unload the pump at low pressure during periods between work cycles.
