Airtac M5R Roller Lever Mechanical Valve M5R11006G
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5R Roller Lever Mechanical Valve M5R11006G is a genuine 5/2-way roller type control valve. A roller lever tripped by a passing cam, slide or carriage. Works from either direction. 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 roller type control set is METAL, which gives a longer service life than the engineering-plastic heads. The exhaust outlet sits on top of the body, so a silencer fits directly.
About the M5R11006G
The AirTAC M5R11006G is a 5/2 way external control, direct acting valve whose spool is thrown by a mechanical roller lever, not by a solenoid coil and not by an air pilot signal. There is no wiring and no pilot port: a cam, carriage or machine slide simply runs over the roller and switches the valve. Because the roller can be tripped from either direction, the valve changes over on both passes and its spring return follows the actuator, so the valve sits in the neutral position whenever nothing presses the roller.
Inside is a sliding-column spool, which means the control force is not affected by working pressure - there is no back-pressure effect, so changeover feels the same at low pressure as at full 1.0 MPa line pressure. The roller lever uses a metal control set for longer service life, the aluminium 100 Series body takes PT1/8 ports with an 8.0 mm2 (Cv 0.45) orifice, and the exhaust outlet sits on top of the body so a silencer screws straight on. If the lever ever wears, a matching metal control set is available as a spare under part number M3R210-P14A, which fits the M5R110 and M5R210.
Typical applications
Transfer carriage on a two-pass cycle
A pneumatic transfer carriage on a machining line runs forward over the roller to fire the clamp cylinder, then trips the same valve again on the return pass to release it - one valve, both directions of travel.
Fixture drawer interlock on a drill jig
Closing the sliding drawer of a drill press fixture pushes the roller down, which switches the valve and extends a locking pin; opening the drawer lets the spring return retract the pin before the drawer is fully clear.
Part stopper at the end of an assembly conveyor
A pallet arriving at a rotary indexing table strikes the roller lever, extending a stopper blade; the spring return drops it as soon as the pallet moves on, resetting the station with no sensor wiring.
How to choose
If you are choosing between the two roller valves in this family, the difference is direction. This M5R trips from either side, so one valve can fire the cylinder on the forward pass and again on the return - the usual choice for end-of-stroke signalling. The M5L is deliberately one-directional: it ignores the return pass entirely, which is what you want when the return stroke must not re-trigger the sequence. Choose R for two-way tripping, L for return-pass-only logic.
This model is the 110 body, the lighter 100 Series single-control housing with an 8.0 mm2 (Cv 0.45) orifice; the 210 body steps up to 9.0 mm2 (Cv 0.50) in 1/8 in or 12.0 mm2 (Cv 0.67) in 1/4 in, so move to 210 if the cylinder is larger. Mind the reversal stroke: the spool moves 2.0-3.0 mm and the roller travels 4.6-6.8 mm, and driving the cam beyond those limits will damage the valve, so design the cam or trip dog to strike within range and stop.
Frequently asked questions
It is a 5/2 way external control, direct acting, mechanically actuated roller valve with no coil and no pilot port. Working pressure is 0-1.0 MPa (0-145 psi) with a proof pressure of 1.5 MPa (215 psi), operating temperature -20 to +70 C, and PT1/8 ports on an aluminium alloy body. The orifice is 8.0 mm2 (Cv 0.45), which is the 110 body figure. Air must be filtered to 40 um, and once lubricated air is introduced (ISO VG32 or equivalent) it should be continued for the life of the valve.
Stay inside the published reversal stroke. For this valve the spool itself moves 2.0-3.0 mm and the roller lever travels 4.6-6.8 mm, and AirTAC states explicitly that exceeding these limits damages the valve. Mount the trip dog or cam so it strikes the roller squarely within that travel and does not slam the lever past full throw - a cam with slight overtravel into a stop, rather than a hard strike, is the reliable way to mount it.
