Airtac M5PF Flat Head Push Button Mechanical Valve M5PF21006R
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5PF Flat Head Push Button Mechanical Valve M5PF21006R 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 9.0 mm2 (Cv 0.50) 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 M5PF21006R
The M5PF21006R is a 5/2 way external control, direct acting valve that is thrown mechanically by a flush flat button - there is no coil, no pilot port and no electrical connection of any kind. A red button sits level with the mounting surface, so a deliberate finger press is needed to actuate it and a passing elbow, tool or part cannot easily trigger it. When the button is released, an internal spring snaps the spool back automatically. It is built on the 200 series single control body with a PT1/8 port.
Flow through the 1/8 inch body gives an effective area of 9.0 mm2 (Cv 0.50). Because the spool is a sliding column, the force needed to change over does not rise with working pressure, so the button feels the same to press at 0.2 MPa as it does 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 is rated for hand operation only - striking it with a mallet or machine part is forbidden by the manufacturer.
Typical applications
Cycle start on a packaging machine
A flush start button on a carton-sealing machine keeps operators from launching a cycle by leaning on the panel. The spring return means the valve signals only while the button is actually held.
Acknowledge station at a clamping fixture
On a pneumatic clamp fixture, an accidental valve hit could release a workpiece mid-operation. The level bezel means a passing sleeve or jig edge cannot trip it - only an aimed press can.
Setup-mode vent for a rotary indexing table
Panel-mounted beside the control cabinet, the valve vents the indexing cylinder while a technician holds the button during manual table positioning, then re-pressurises the moment the hand lifts.
How to choose
The button family splits on one question: how easy should this valve be to hit? The flush PF here is the deliberate-choice option - the button is level with its bezel and needs an aimed press, which is exactly what you want at a cycle-start or acknowledge station. If operators must find the button without looking, the protruding PP or the large palm-size PM is the better pick; if the state must hold after pressing, leave the spring-return family entirely and specify the PL latching type. On body and port, this 210 model with a PT1/8 port flows 9.0 mm2 (Cv 0.50); stepping to the 210 1/4 inch port raises that to 12.0 mm2 (Cv 0.67) for larger cylinders. Mind the stroke limits: the spool is fully thrown within 2.0-3.3 mm and the button travels only 3.8-5.1 mm - pressing beyond these figures damages the valve.
Frequently asked questions
It is a 5/2 way external control, direct acting valve operated by a red flush flat button with automatic spring return. Working pressure is 0-1.0 MPa (0-145 psi) with a proof pressure of 1.5 MPa (215 psi), and it runs on filtered air from -20 to +70 C. The port is PT1/8 on the 200 series body, with an effective area of 9.0 mm2 (Cv 0.50). The aluminium body supports both body and panel mounting.
The spool is fully thrown within 2.0-3.3 mm of travel and the button itself moves only 3.8-5.1 mm. Those are published limits, not guidelines: pressing or striking past them can damage the engineering plastic control set, which is a hand-operated part that must never be hit with a tool. Because the button is flush, only a deliberate press reaches it in normal use, which protects both against accidental actuation and against overtravel.
