ODE 21A3KV20 is a 21A Series direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seals

ODE 21A3KV20 is a 21A Series direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seals. It is designed for high-pressure control of water, air, steam, fuel gases, and other compatible industrial fluids.

Operating Principle

  • De-energized (power OFF): Valve remains closed.
  • Energized (power ON): Valve opens.
  • Direct-acting design allows operation from zero differential pressure.
  • Construction
  • Brass body (CW617N)
  • Stainless steel armature tube
  • Stainless steel plunger
  • Stainless steel spring
  • FKM (Viton®) seals

Typical Applications

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