ODE 21A3KV45 is a 21A Series, 2/2-way, direct-acting, Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seal

ODE 21A3KV45 is a 21A Series, 2/2-way, direct-acting, Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seal. It is designed for higher-flow industrial applications involving air, water, inert gases, oils, and other compatible fluids.

Operating Principle

  • Power OFF: Valve remains closed.
  • Power ON: Valve opens.
  • Direct-acting construction allows operation from 0 bar differential pressure.

Construction Materials

  • Brass valve body (CW617N)
  • Stainless steel armature tube
  • Stainless steel plunger
  • Stainless steel spring
  • FKM sealing elements

Typical Applications

  • Industrial automation
  • Compressors
  • Water treatment systems
  • Steam service
  • Fuel gas systems
  • Coffee and vending machines
  • Packaging machinery
  • Car wash equipment
