Description:
DURAVIS ESV 620 and 621 Series direct acting stainless steel solenoid valves are suited for what we call a general purpose and slightly aggressive valve material is stainless steel media applications, such as compressed air, mains water systems, vacuum, Argon, Helium, Oxygen, Nitrogen, process water, pure water, demineralised water, RO water, sodium hydroxide, light oils, steam, diesel, petrol, final effluent, aviation fuels and basically any non or slightly aggressive or corrosive liquid or gas media and environment.
The direct-operated ESV 620 and 621 series solenoid valves consist of a coil, plunger, and sleeve assembly. ESV 620 are normally closed valves while ESV 621 series are normally open.
