The ODE 21WA4K0B130 is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve intended for water, air, and inert gas applications where higher flow capacity is required.

The ODE 21WA4K0B130 is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve intended for water, air, and inert gas applications where higher flow capacity is required.

Part Number Breakdown

  • 21WA = Pilot-operated valve series
  • 4 = G 1/2" port size

K0 = Normally Closed (NC)

  • B = NBR seal
  • 130 = 13 mm orifice

Typical Applications

  • Water treatment systems
  • Compressed air systems
  • Industrial automation
  • Packaging machinery
  • HVAC systems
  • Cooling and heating equipment
  • General industrial process control

Quick Summary

The 21WA4K0B130 offers a larger G 1/2" connection and higher flow capacity than the 21WA3K0B130, while retaining the same NBR sealing and operating pressure range.
