ODE 21A8KV45 is a 21A Series direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seal

ODE 21A8KV45 is a 21A Series direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and FKM (Viton®) seal. It is intended for water, air, inert gases, oils, fuel gases, and other compatible industrial fluids.

Operating Principle

  • De-energized (Power OFF): Valve remains closed.
  • Energized (Power ON): Valve opens.
  • Direct-acting construction means no minimum differential pressure is required for operation.

Typical Applications

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

2/2-way Normally Closed

  • Direct-acting solenoid valve
  • G 1/2" BSP connection
  • 4.5 mm orifice

Kv = 6.5 L/min

  • FKM (Viton®) seal
  • 0 to 12 bar operating pressure
  • 10°C to +140°C fluid temperature range
