INTRODUCTION & FEATURES IN BRIEF

OPERATOR HEA D General Features 1.350 bar service.2.Sizes from DIN 016 to DIN 100.3.Slip-in cartridge insert valves can provide the following functions:a)Check valve.b)Flow control.c)Pressure regulating.d)Directional control.e)Decompression control.f)Special combinations.4.A single cartridge can provide more than one function with properoperator circuiting.5.Cartridges of the same size butdifferent ratios are interchangeable.6.Cartridges are small, compact and handle high flow rates.7.Individual cartridges can be sized to satisfy circuit flow rates.8.Different size cartridges (withspacers) can be designed into acommon manifold eliminatingnecessity for angular drilling.9.Cartridges can be installed in amanifold at right angles to each other or even reversed from standard position to simplify manifoldmachining.
