Airtac M5PL Detent Rotary Push Button Type Mechanical Valve M5PL11006
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5PL Detent Rotary Push Button Type Mechanical Valve M5PL11006 is a genuine 5/2-way latching type control valve. Press to latch, twist the button to release. Manual restoration, red only. 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 M5PL11006
The AirTAC M5PL11006 is a 5/2 way, external control, direct acting valve that is thrown entirely by hand - there is no coil, no pilot port and no electrical connection anywhere on it. Its latching actuator works in two deliberate steps: press the red button once and the spool stays in its new position; twist the button and it releases back. That hold is mechanical, so the valve keeps its state through a loss of air, a shift change or a power cut at the station.
This example uses the 100 Series single control body with PT1/8 ports and an effective area of 8.0 mm2 (Cv 0.45). The latching control set is engineering plastic and is intended for manual operation only - the datasheet forbids striking it with a tool, so reach for the M5C or M5D long or short handle if the valve will see mallet or fixture contact. Because the spool is a sliding column, the force needed to latch it does not rise with working pressure, so the changeover feels the same at 0.2 MPa as it does at 1.0 MPa. The exhaust outlet sits on top of the body, so a silencer screws on without re-plumbing anything.
Typical applications
Clamp circuit isolation on a welding fixture
Press the button to latch and vent the clamp cylinders so a welder can load and unload brackets on a robot welding cell; twist to release and the clamps re-pressurise on the next air cycle. The held state survives the vibration of the weld itself.
Tool change hold on a pneumatic press die
Latching the 5/2 locks the die cushion or ejector circuit in a safe vented condition while the setter swaps tooling, and the twist-to-release action is a conscious second step rather than something a passing sleeve can undo.
Mode hold on a packaging machine reject gate
Latch the valve to divert the reject chute to a manual inspection bin during a quality check, then twist to release and restore automatic diversion - no solenoid circuit has to be patched into a machine that is otherwise purely pneumatic.
How to choose
The choice you are most likely weighing is PL versus HS. Both hold their state - the difference is the gesture. The HS selector turns and stays, which suits a panel where an operator should see position at a glance; this PL presses to latch and twists to release, which suits a fixture where the state must survive vibration but a plain twist must not be able to knock it over. If you actually need spring return, the PF or PP buttons reset automatically the moment you lift off. On body and port: this 110 body flows 8.0 mm2 (Cv 0.45) through PT1/8; stepping to the 210 body gives 9.0 mm2 at 1/8 or 12.0 mm2 (Cv 0.67) at 1/4 for a larger cylinder.
Respect the published reversal strokes: spool stroke 2.0-3.3 mm and button travel 5.9-7.2 mm. Pressing past these limits damages the valve, and AirTAC says so explicitly - the latch mechanism is not a guard against over-travel. Control sets are orderable separately as spares, so a worn latching head does not condemn the whole valve.
Frequently asked questions
It is a 5/2 way external control, direct acting, mechanically latched valve with PT1/8 ports. Working pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), and the temperature range is -20 to +70 C with air filtered by a 40 um element. Effective area on the 110 body at 1/8 is 8.0 mm2 (Cv 0.45). Body is aluminium alloy, lubrication is not required, and once lubricated air (ISO VG32 or equivalent) is introduced it should be continued.
The spool stroke is 2.0-3.3 mm and the button travel is 5.9-7.2 mm; those are the published limits. Driving the button past them damages the valve - AirTAC states this explicitly in the datasheet. Also note the control set is engineering plastic meant for hand operation only: striking it with a tool is forbidden, and the red button releases by twisting, never by pressing again.
