Airtac M5HS Selector Mechanical Valve M5HS11006BG
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5HS Selector Mechanical Valve M5HS11006BG is a genuine 5/2-way selector switch type control valve. A turn-and-stay selector. Manual restoration, so it holds the selected state. 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 M5HS11006BG
The M5HS11006BG is a 5/2-way external control, direct acting valve that is turned by hand - there is no coil, no pilot port and no electrical connection anywhere on it. A black selector switch sits on a 100-series single control body with G1/8 threads: twist the selector and it stays in the position you left it, so the downstream cylinder holds its state until a person deliberately turns the switch back. With an effective area of 8.0 mm2 (Cv 0.45), it is sized for small cylinders and signal-duty circuits.
Inside, a sliding-column spool does the switching, which means the force needed to turn the selector is not affected by working pressure - there is no back-pressure effect, so the changeover feels and performs 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 straight on without an elbow. The selector's engineering plastic control set is for hand operation only: AirTAC forbids striking it with a tool, unlike the metal control sets fitted to the roller and lever versions in this family. Body mounting and panel mounting are both supported, and replacement control sets can be ordered as spares.
Typical applications
AUTO/MANUAL mode selection on a packaging machine
Turn the selector to route air to the automatic cycle circuit or hand-test circuit on a carton sealing line. Because it is a turn-and-stay switch, the machine stays in whichever mode was set, even after a shift handover or a control-air interruption and restore.
Hold-open state for a laboratory fume cupboard sash purge
The selector latches a vent-actuation circuit on for a scheduled purge without anyone holding a button. Manual restoration means only a deliberate twist cancels the state - an accidental brush against the panel cannot drop the circuit.
Clamp-isolation position on a welding jig for tool change
Twist the selector to vent the clamp cylinders, leaving the jig safely unclamped while dies or fixtures are swapped, then twist back to restore the clamped circuit. The held position removes any doubt about which state the jig is in mid-change.
How to choose
You are almost certainly choosing between the three hold-position actuators on this body. If the operator should twist rather than pull or press, HS is right; the Y lever is better where a gloved hand wants a visible lever angle, and the PL latching button suits a fault-acknowledge style press-then-twist-to-release action rather than a sustained mode selection. Pick HS when the state must persist through shift changes and nobody should be able to bump it out of position. On body and port: the 110 body at 8.0 mm2 (Cv 0.45) with this G1/8 thread covers small cylinders and pilot signals; stepping to the 210 body raises the orifice to 9.0 mm2 at 1/8 or 12.0 mm2 (Cv 0.67) at 1/4 for larger actuators.
Respect the published reversal stroke: the spool must travel between 2.0 and 3.3 mm and the selector itself between 5.1 and 6.4 mm. Driving the switch past those limits damages the valve - AirTAC states this explicitly - so the detent must stop at the end of travel, not over-travel through it.
Frequently asked questions
It is a 5/2-way external control, direct acting, mechanically actuated valve with a turn-and-stay selector switch. Working pressure is 0-1.0 MPa (0-145 psi) with a proof pressure of 1.5 MPa (215 psi), and the temperature range is -20 to +70 C. The port is G1/8 on a 100-series (110) single control body, with an effective area of 8.0 mm2 (Cv 0.45). The medium is air filtered by a 40 um element; lubrication is not required, but if lubricated air is used, keep to the same medium - AirTAC suggests ISO VG32 or equivalent.
The published reversal stroke is 2.0-3.3 mm at the spool and 5.1-6.4 mm at the selector. These limits are not guidelines - AirTAC warns that exceeding them damages the valve. Because the selector is a turn-and-stay device with a defined end of travel, mounting should allow the operator's hand or a guard to stop naturally at the detent. Note also that this HS control set is engineering plastic and is rated for hand operation only; striking it with a tool is forbidden, which is one reason the metal control sets on the roller and handle versions exist.
