Airtac M5PP Poppet Push Button Mechanical Valve M5PP11006B
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5PP Poppet Push Button Mechanical Valve M5PP11006B is a genuine 5/2-way protruding button type control valve. A raised button - quick to find, still guarded against a full palm strike. 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 M5PP11006B
The M5PP11006B is a 5/2 way, externally controlled, direct acting mechanical valve. There is no solenoid coil and no pilot port: the spool is thrown by pressing the raised protruding button with a finger, knuckle or palm, and a spring snaps it back the moment you let go. It is built on the 100 series single-control (110) body with a 1/8in PT port and an effective area of 8.0 mm2 (Cv 0.45). If a buyer arrived here from a 4V solenoid search, this is the keyless, wire-free equivalent - the valve changes over whenever something physically pushes it.
Construction details worth knowing before you install it. The sliding-column spool means the force needed to change over is not affected by working pressure, so there is no back-pressure effect and the button feels identical at 0.2 MPa and at 1.0 MPa. The exhaust outlet sits on top of the body, so a silencer screws straight in without re-plumbing. The control set is engineering plastic and this unit is strictly for manual operation - the datasheet forbids switching it by striking with a tool. Both body mounting and panel mounting are supported, and a spare control set can be ordered separately if you want one on the shelf.
Typical applications
Bench jig clamp on a drill fixture
Panel-mount the valve beside a drill jig so the operator presses the raised button to throw air to the clamp cylinder and simply releases to unclamp - the spring does the reset, so one hand never leaves the workpiece.
Jog advance on a packaging conveyor
A protruding button suits a conveyor control panel where an operator nudges product forward a step at a time: press for forward, release and the spring returns the valve to its home position automatically.
Purge blow-off on a leak-test bench
On a pneumatics test rig, use the raised button as a momentary purge control to blow filtered air through a test circuit; the exhaust sits on top of the body, so a silencer screws straight in to keep the bench quiet.
How to choose
The choice you are really making is between the three button heads. This PP protruding button is raised above the panel, so an operator can find and press it without looking - pick it over the PF flat button when the valve sits on a crowded fixture and must be easy to hit deliberately. Choose PF instead when accidental operation is the bigger risk, and PM mushroom when the largest possible target matters more than panel space. On bodies: the 110 gives you 8.0 mm2 (Cv 0.45) at 1/8in, while stepping up to a 210 body gets 9.0 mm2 at 1/8in or 12.0 mm2 (Cv 0.67) at 1/4in - size the port to the cylinder bore and flow you need.
One warning that is easy to miss: the spool stroke is 2.0-3.3 mm and the button stroke is 3.8-5.1 mm. Those are published limits, not suggestions. Exceeding them - by hammering the button or letting a link bottom out on it - damages the valve, and AirTAC says so explicitly. Mount it so the press travels free and stops just past full stroke.
Frequently asked questions
It is a 5/2 way, externally controlled, direct acting mechanical valve with a protruding button and automatic spring return. Working pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -20 to +70 C. The 110 body has a 1/8in PT port with an effective area of 8.0 mm2 (Cv 0.45), an aluminium alloy body, and runs on air filtered by a 40 um element. No lubrication is required, but once lubricated air is introduced keep using it - ISO VG32 or an equivalent grade.
The published reversal stroke is 2.0-3.3 mm at the spool and 3.8-5.1 mm at the button. These are hard limits: driving the button past full stroke - by striking it with a tool or letting a mechanical linkage bottom out - damages the valve. Note too that the plastic control set is rated for manual operation only, so never switch this valve by hitting it. Mount it so the button travels freely and any actuating stop clears at full stroke.
