ODE 21A5KT45 is a 21A Series, direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and PTFE seal

ODE 21A5KT45 is a 21A Series, direct-acting, 2/2-way Normally Closed (NC) solenoid valve with a brass body and PTFE seal. It is specifically suited for higher-temperature media such as steam and aggressive fluids where PTFE sealing is required.

Operating Principle

  • Power OFF: Valve remains closed.
  • Power ON: Valve opens.
  • Direct-acting construction allows operation from zero differential pressure.

Suitable Media

With PTFE seals, this valve is suitable for:

  • Steam
  • Hot water
  • Aggressive chemicals
  • Air and inert gases
  • Industrial process fluids

The PTFE version supports a wider temperature range than FKM or NBR versions.

  • Applications
  • Steam systems
  • Industrial automation
  • Process heating equipment
  • Packaging machinery
  • Water treatment
  • Compressors
  • Chemical process systems
