DF260-360 Miniature Solenoid Valves

Solenoid Valves for medical analysers, biotechnology, gas analysers; Can be used to control acids and bases, analytical reagent FEATURES• Valves for medical analysers, biotechnology, gas analysers• Can be used to control acids and bases, as well as analytical reagents• Any application where the fluid may not come into contact with metal parts andwith the electromagnetic control section of the solenoid valves• The valves are ideal for controlling aggressive fluids or when high purity is demandedand have easy to flush internal cavities• They can also be used as a very small internal volume flow-through samplingvalve due to rocker technology• Hermetic separation of control mechanism and fluid• Reduced heat exchange between coil and fluid• Protected manual operator• The use of first class materials and thorough valve testing ensure high reliabilityand a lifetime of at least 2 million cycles• The solenoid valves satisfy all relevant EC directives GENERAL
