ODE 21H9KB180 is a 21H Series, 2/2-way Normally Closed (NC), pilot-operated solenoid valve designed for high-flow applications involving water, air, inert gases, and other fluids compatible with NBR seals

ODE 21H9KB180 is a 21H Series, 2/2-way Normally Closed (NC), pilot-operated solenoid valve designed for high-flow applications involving water, air, inert gases, and other fluids compatible with NBR seals. It uses a brass body, a large 18 mm orifice, and requires a minimum differential pressure of 0.1 bar to operate.

Operating Principle

  • Power OFF: Valve remains closed.
  • Power ON: Pilot section opens the diaphragm and allows full flow.
  • Requires a minimum 0.1 bar pressure differential because it is a pilot-operated design.

Seal Characteristics

The NBR version is suitable for:

  • Air
  • Water
  • Inert gases

Temperature range:

−10°C to +90°C with NBR seals.

Typical Applications

  • Water treatment systems
  • Industrial automation
  • Industrial washing machines
  • Packaging equipment
  • Thermoregulation systems
  • Car wash systems
  • Air handling systems

Key Summary

  • Model: ODE 21H9KB180
  • Type: Pilot-operated, 2/2-way Normally Closed
  • Connection: G 3/4" BSP
  • Seal: NBR (Nitrile)
  • Orifice: 18 mm
  • Flow Capacity: 50 L/min
  • Pressure Range: 0.1 to 16 bar
  • Temperature Range: −10°C to +90°C
  • Body Material: Brass
