About the Airtac CM3PF Flat Push Button Mechanical Valve CM3PF05B
With its flush push button head in black, the AirTAC CM3PF05B is a 3/2-way mechanical valve with M5 ports. It is worked by hand, as a simple control for an air circuit at the machine or on a panel. At the M5 port the effective area is 2.0 mm2 (Cv 0.11).
It is a poppet valve, so it seals tightly and switches cleanly. It runs on air filtered to 40 um from 0 to 1.0 MPa (0-145 psi), with 1.5 MPa (215 psi) proof pressure, at -20 to +70 C. No lubrication is needed. M5 ports carry no thread suffix.

How to choose
This code uses the M5 port (2.0 mm2, Cv 0.11); the same PF head also comes with 1/8 (06, Cv 0.14) and 1/4 (08, Cv 0.84). A larger port passes more air when the valve drives a cylinder or a long pilot line directly. The color letter after the port is B (black) here; CM3PF05R red, CM3PF05G green and CM3PF05Y yellow are the other colors of this head. Other hand-operated heads: rocker lever (Y), turn-release latching button (PL), extended push button (PP), mushroom push button (PM), mushroom button with guard (PMS), large mushroom button with guard (PMX), selector switch (HS) and two-way selector switch (HD).
Applications
Start button on a panel
A push button starts an air cycle at the operator panel.
Air-only control desks
Air buttons work where electric switches are not wanted, with no wiring in the panel. The M5 port gives Cv 0.11.
Two-hand and sequence circuits
Sends a pilot signal into an air logic circuit when pressed.
FAQ
What are the key figures of the CM3PF05B?
3/2-way mechanical valve, flush push button head (PF), black; M5 ports, effective area 2.0 mm2 (Cv 0.11); 0 to 1.0 MPa (0-145 psi), proof 1.5 MPa (215 psi); -20 to +70 C; air filtered to 40 um; aluminum-alloy body.
What does the B in CM3PF05B mean?
It is the color letter of the flush push button: B = black. Only the push-button and selector heads take a color letter (R red, G green, B black, Y yellow).
