The ODE 21A2ZV45D is a 21A Series direct-acting, 2/2-way Normally Open (NO) solenoid valve manufactured by ODE S.r.l.

The ODE 21A2ZV45D is a 21A Series direct-acting, 2/2-way Normally Open (NO) solenoid valve manufactured by ODE S.r.l.. It is designed for controlling water, air, inert gases, oils, and other compatible industrial fluids.

Operating Principle

  • De-energized (power OFF): Valve remains open.
  • Energized (power ON): Valve closes.
  • Being a direct-acting valve, it does not require a minimum pressure differential to operate.

Construction Materials

  • Brass body
  • Stainless steel armature tube
  • Stainless steel plunger
  • Stainless steel spring
  • FKM (Viton®) seals

Typical Applications

  • Water treatment systems
  • Industrial automation
  • Packaging equipment
  • Compressors
  • Coffee and vending machines
  • Thermoregulation systems
  • Air and inert gas control
