Airtac M5PF Flat Head Push Button Mechanical Valve M5PF11006R
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5PF Flat Head Push Button Mechanical Valve M5PF11006R is a genuine 5/2-way flat button type control valve. A flush button, hard to operate by accident. It is an external control, direct-acting valve - the spool is moved mechanically, so there is nothing to wire and no pilot line to plumb. Ports are PT1/8 with a 8.0 mm2 (Cv 0.45) effective area.

Sliding-column (spool) construction, so operating force is not affected by working pressure - there is no back-pressure effect. Lubrication is not required, but once the valve has been run on lubricated air it must stay on lubricated air; AirTAC suggests ISO VG32 or equivalent. The control set is engineering plastic and must be operated by hand only - never switch it by striking it with a tool. The exhaust outlet sits on top of the body, so a silencer fits directly.
About the M5PF11006R
The M5PF11006R is a 5/2-way, direct acting valve that is thrown purely by hand: a fingertip presses the flush button on top of the body and the spool changes over. There is no solenoid coil, no pilot port and no wiring of any kind, so it belongs to the mechanical M5 family and not to the electrically switched 4V range. Press the button once and air passes to one cylinder port; let go and the internal spring returns the spool, venting through the exhaust. The 100-series (110) body takes 1/8in PT threads and breathes through an effective area of 8.0 mm2 (Cv 0.45).
Inside is a sliding-column spool, so the force needed to change over is the same whether the downstream line is empty or sitting at the full 1.0 MPa - there is no back-pressure effect pushing back against your finger. The aluminium body can be screwed down directly or panel mounted, and because the exhaust outlet sits on top of the body a silencer screws straight in without an elbow. The control set is engineering plastic and is intended for hand operation only; the datasheet explicitly forbids striking the button with a tool.
Typical applications
Bench drilling fixture clamp
Mounted on the jig plate, the flush button starts the clamp cylinder only when the operator deliberately presses it; the flush profile stops swarf, tools or a resting forearm from triggering a cycle by accident, and the spring returns the valve the moment the hand lifts.
Manual single-cycle station on a small packaging machine
Fitted at the side of the frame, the valve gives a one-shot pneumatic signal for a test or jog stroke without any electrical interface. Its flat head keeps the control flush with the guard panel, and because there is no coil it works even with the machine's control power isolated.
Pneumatic test rig in the lab or workshop
On a rig building prototypes with filtered air, the valve switches a test cylinder between extend and retract with a simple press. The sliding-column spool changes over identically from zero pressure up to 1.0 MPa, so results stay repeatable across the whole test range.
How to choose
The button family splits into flat (PF), protruding (PP) and mushroom (PM), and the difference is how easily the valve can be hit by mistake. The PF flush button sits level with its collar, so a sleeve, elbow or falling part brushing past will not operate it - choose it where a false signal would start a machine. Pick the PP protruding button when the operator must find the control without looking, or the PM mushroom head when a palm strike is wanted. If the valve must hold its position after the hand leaves it, step to the manual-restoration Y lever, HS selector or PL latching types instead of this spring-return model.
Body-wise, staying on the 110 body at 1/8in gives 8.0 mm2 (Cv 0.45); moving to the 200-series body at 1/8in raises this to 9.0 mm2 (Cv 0.50), and the 210 body at 1/4in reaches 12.0 mm2 (Cv 0.67) for larger cylinders. Mind the reversal stroke: the spool travels 2.0-3.3 mm and the button 3.8-5.1 mm. Pressing beyond those figures damages the valve, so mount it so the operator cannot bottom the button out against a fixed stop.
Frequently asked questions
It is a 5/2-way, external control, direct acting valve operated by a flush (flat) button with automatic spring return. Working pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), and media temperature -20 to +70 C with air filtered by a 40 um element. The 110 body has 1/8in PT ports and an effective area of 8.0 mm2 (Cv 0.45). The body is aluminium alloy, and lubrication is not required - though once lubricated air is introduced, keep using the same medium (AirTAC suggests ISO VG32) for best valve life.
The published reversal stroke is a spool stroke of 2.0-3.3 mm with a total button stroke of 3.8-5.1 mm. These are hard limits: pressing the button past the end of its stroke damages the valve, and AirTAC states this explicitly in the datasheet. Mount the valve so the button cannot be bottomed against a panel or bracket, and train operators to a normal press-and-release action rather than a hard push.
