Airtac M5HS Selector Mechanical Valve M5HS11006B
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5HS Selector Mechanical Valve M5HS11006B 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 M5HS11006B
The M5HS11006B is a 5/2-way external control, direct acting valve that is thrown by hand - you twist the selector knob and it stays exactly where you put it. There is no solenoid coil and no pilot port anywhere on this body: it is not a 4V solenoid valve and not a 4A air pilot valve, and nothing electrical is needed to make it switch. The 100-series (110) single-control body takes a 1/8in PT thread and breathes through a 8.0mm2 effective orifice (Cv 0.45).
Inside, a sliding-column spool does the changeover, and because the spool moves on the selector stroke rather than against line pressure, the control force does not change with working pressure - there is no back-pressure effect, so the knob feels the same at 0.2 MPa as it does at 1.0 MPa. The selector carries an engineering plastic control set, which is strictly for hand operation: never strike it with a tool. AirTAC sells replacement control sets separately, so a worn knob does not mean a new valve. The exhaust port sits on top of the body, so a silencer screws straight in without rerouting tubing, and the valve mounts either on its body footprint or flush in a panel.
Typical applications
Mode selector on a packaging machine
Mounted on the control panel of a carton-sealing line, the selector lets one operator twist between setup mode and run mode. The valve holds the chosen 5/2 position without air or power, so the machine cannot drift back to run while a guard is open.
Clamp isolation on a welding fixture
Fitted beside the pneumatic clamps of a welding jig, the turned-and-held position blocks the clamp supply during part loading. The state stays put with no latching spring to fight, and the top exhaust port takes a silencer right at the fixture.
Gate hold on a bottling conveyor
A selector at the infeed of a bottle rinsing line holds the gate cylinder in the closed 5/2 state during changeover between bottle sizes. Because switching force is unaffected by line pressure, the knob turns identically whether the header tank is at 0.3 or 0.8 MPa.
How to choose
The HS selector sits in a three-way decision about holding state. If an operator only needs to flip a valve and have it stay - selecting auto or manual mode on a machine - HS is the clean answer: twist, release, and the position is held. If the state must latch after a momentary press and be released with a deliberate twist of the button, step to the PL latching type; if a lever is preferred over a knob, the Y lever type also holds position manually. All three differ only in the actuator on the same valve platform.
On body and port: this 110-body 1/8in version flows 8.0mm2 (Cv 0.45). Stepping to the 200-series (210) body raises flow to 9.0mm2 at 1/8in or 12.0mm2 (Cv 0.67) at 1/4in, and adds button colour coding - useful if you later want a colour-coded selector station. Size the port to the cylinder being piloted or shifted. Mind the published reversal strokes: spool stroke 2.0-3.3mm, selector stroke 5.1-6.4mm. Over-travel beyond these limits damages the valve - fit a positive stop if a heavy hand is likely.
Frequently asked questions
It is a 5/2-way external control, direct acting valve with selector switch (HS) actuation and manual restoration - turn and stay. Port size is PT1/8 on the 100-series (110) body, with an effective area of 8.0mm2 (Cv 0.45). Working pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), and media temperature -20 to +70 C on filtered air (40um element). The aluminium alloy body needs no lubrication; if lubricated air is used, keep the same medium, ideally ISO VG32.
The published reversal strokes are 5.1-6.4mm at the selector and 2.0-3.3mm at the spool. These are hard limits, not guidelines: AirTAC states explicitly that exceeding them damages the valve. Because the knob is meant for a deliberate hand turn rather than a hammer or bar - and the plastic control set is rated for manual operation only - panel the valve so the knob cannot be forced past its stop, and order a spare control set if the station sees rough duty.
