  • TypeDrain Components
  • Three-way valve directs airflow in two positions
  • Roller-spring actuator returns lever automatically
  • Rated for 150 psi working pressure
  • Operates from 32 to 175 degrees F
  • Aluminium body measures 4 3/16 in long

DirectAir 2 3-Way Valve

The Parker 404211000 is a 3-way, 2-position manual air control valve built for pneumatic circuits. Its aluminum body measures 4 3/16 inches long with a 1/8 inch NPT port. The DirectAir 2 series design suits automation and machine-tool applications needing reliable directional control.

Verify Port Size and Pressure

Confirm your system uses 1/8 inch NPT threads before ordering. The valve handles up to 150 psi and flows 0.17 cfm at a Cv of 0.2. Operating temperature range is 32 to 175 degrees F. The spring-return actuator requires no external pilot signal.

Replaces Stuck or Leaking 3-Way Valves

Swap this in when an existing 3-way valve leaks, sticks, or fails to return. The closed-center function holds position on loss of actuation. The jump is worth it if you need a compact aluminum body with a 5/8 inch width for tight manifolds.

Questions about this item

What comes with the Parker 404211000 valve and what fittings must be purchased separately?

The valve body is supplied alone. You will need 1/8 NPT pipe fittings or tubing adapters to connect it to your air lines.

How do I choose between the available versions of this 3-way manual air control valve?

Only one version is offered: 3-way, 2-position, 1/8 NPT, spring-return roller actuator, aluminium body, 0.17 CFM at 150 psi. Select it when those specifications match your circuit requirements.

What does the 0.17 CFM rating mean when the valve is installed in a pneumatic system?

At 150 psi supply pressure the valve passes 0.17 cubic feet of air per minute, so size upstream compressors and downstream actuators to stay within that flow limit.
