21WA4K0B130-M

The ODE 21WA4K0B130-M is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve for water, air, and inert gas applications

The ODE 21WA4K0B130-M is a 2/2-way Normally Closed (NC), pilot-operated solenoid valve for water, air, and inert gas applications. The “-M” suffix generally identifies a special version of the standard valve, commonly used for specific mounting or application requirements while maintaining the same hydraulic characteristics as the base model.

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
• M = Special version / manufacturer-specific modification code

Typical Applications

• Water treatment systems
• Air distribution systems
• Industrial automation
• Cooling and heating systems
• Process control equipment
• Compressors
• Packaging machinery

Quick Summary

Note: The hydraulic performance of the 21WA4K0B130-M is generally the same as the standard 21WA4K0B130. The “-M” suffix indicates a manufacturer-specific variant, and the exact difference (mounting, manual operator, coil configuration, or special option) depends on the ODE ordering code for that specific valve.
