Helpful for Model Matching:

  • Full M3 code or readable actuator/valve label
  • Mini 05 with B/R/L; size 110 with 06 only; size 210 with 06/08
  • For 210, colored buttons use R/G/B; PL has a blank color code for red. Size 110 has no color code.
  • Return behavior, actuation direction, stroke limits and the matching actuator drawing
  • Select the drawing for the exact actuator and mini or common size; other head geometries have different dimensions.
  • Verify return mode, head travel and the L direction from right to left.
  • Body dimensions and actuator accessory drawings are separate evidence. Accessory codes do not identify complete valves.

Catalogue Technical Specifications

AirTAC reference data
Function / actuationExternal control, direct acting, 3/2. B/R/L are mechanically actuated; C/D/Y/PL/PP/PF/PM/HS are manually operated.
Ports / flowMini 05 M5: 2.5 mm²/Cv 0.14; 110 06 1/8: 8.0/Cv 0.45; 210 06 1/8: 9.0/Cv 0.50; 210 08 1/4: 12.0/Cv 0.67.
PressureWorking 0–1.0 MPa (0–145 psi); proof 1.5 MPa (215 psi).
Medium / temperature / bodyAir filtered through a 40 μm element; −20 to +70 °C; aluminum alloy.
Return behaviorAutomatic return: B/C/D/PM/PF/PP. Manual return: Y/HS/PL; PL resets by rotating the depressed button. Confirm R/L return behavior from the installed mechanism.
L directionL switches only when impacted from right to left. The opposite direction does not switch. Verify installed roller orientation.
Stroke / installationDo not exceed the published reversal stroke. Body and panel mounting are shown. Do not strike engineering-plastic manual heads with metal.
LubricationLubrication not required. Once lubricated, continue the same medium; ISO VG32 or equivalent is recommended.
Actuator accessoriesRoller accessories: M3R/L05-P14A or M3R/L210-P14A. C/D handles and Y lever use 210-P13A codes. PL/PM/PP/PF/HS use S3-prefixed control-set codes. These are accessories, not complete valves.

B/C/D/Y/R/L/PL/PP/PF/PM/HS; mini only B/R/L.Mini 05 = M5; size 110 uses 06 = 1/8; size 210 uses 06/08 = 1/8 or 1/4.Size 110 has no color code. Size 210 colored buttons use R red, G green or B black; PL has a blank color code for red. Other heads omit color.Common sizes: blank PT, G or T=NPT. Mini M5 has no thread code.

Avoid a wrong match

  • Do not confuse the M3 3/2 family with the M5 5/2 family.
  • Mini uses B/R/L with 05 only; 110 uses 06 only; 210 uses 06/08.
  • 110 has no color code: confirm physical head color separately. For 210, PL is red with a blank color code; other colored buttons use R/G/B.
  • Y/HS/PL require manual return; PL resets by turning the depressed button. PM is not a latching PL.
  • L switches only from right to left. Keep within stroke limits and do not strike plastic manual heads with metal.
  • S3 and actuator accessory codes are not complete valves. Send labels or photos to confirm supply scope.

Read the model code

If the label is incomplete, send the readable parts together with a photo.

About M3

M3 is an externally controlled, direct-acting 3/2 family with mechanical and manual actuator heads. Mini M5 variants use B/R/L; common 110 and 210 offer eleven head types. Match the exact head, size, port, color field and return behavior.

Matching Questions

Do all M3 heads return automatically?

No. The catalogue explicitly lists B/C/D/PM/PF/PP with automatic return and Y/HS/PL with manual return. PL resets by rotating the depressed button. Confirm roller R/L behavior and installation separately.

What direction operates M3L?

Only impact from right to left switches the L free-return roller. The opposite direction does not. Send the roller orientation and required stroke for confirmation.

Does a control-set accessory code order the complete valve?

No. Actuator accessories such as M3R210-P14A or S3PM05-P12A are listed separately from complete M3 valves. Send the valve code, head function, color, quantity and destination, or specify that only a replacement head is needed.
