Airtac M5HS Selector Mechanical Valve M5HS21006B
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5HS Selector Mechanical Valve M5HS21006B 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 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 M5HS21006B
The M5HS21006B is a 5/2-way external control, direct acting valve that is operated by hand - there is no coil, no pilot port and no wiring of any kind. A black selector knob sits on a 200-series single control body, and the spool moves only when a person turns it. If you arrived here from a solenoid valve search, this is the purely mechanical alternative for places where electricity is absent, unwanted or unsafe.
Turn the selector and it stays: this is manual restoration, so the valve holds whichever position you leave it in until someone turns it back. The PT1/8 ported 210 body gives an effective area of 9.0 mm2 (Cv 0.50). Because the sliding-column spool is not influenced by working pressure, there is no back-pressure effect, so the changeover feels and behaves the same from 0 to 1.0 MPa. The exhaust port sits on top of the body, so a silencer screws straight on without bracketing or re-plumbing.
Typical applications
Jog/auto mode selection on a packaging machine
Mount the selector on the control panel of a cartoning or filling machine so an engineer turns to jog mode during setup and back to auto for production. The turn-and-stay action means the mode cannot drift until someone deliberately changes it.
Isolating a clamp circuit during tool change on a press fixture
Fit the valve at the bench of a pneumatic clamping fixture so a setter turns it to dump the clamp circuit before changing tooling. Because restoration is manual, the isolation holds for as long as the job takes, with no spring to re-pressurise the circuit mid-change.
Circuit direction selector on a pneumatics training bench
Use the selector on a technical college or lab bench to switch a demonstrator rig between two circuit states by hand. With no electronics involved, students see pure pneumatic switching, and the top-mounted exhaust keeps a silencer fitting simple.
How to choose
The choice you are really making is between the three holding actuators. The HS selector is turned, so the state is visible and deliberate - ideal where an operator must see at a glance whether a circuit is in mode A or mode B. The M5PL latching button holds too, but it reads as a press-and-release action and is red only; the M5Y lever holds with a flick. If your state must spring back when released, you want an automatic restoration type instead, such as the M5PF flat button or M5PM mushroom head on the same 210 body.
On size: the 110 body (8.0 mm2, Cv 0.45) is the compact step down, while the 210 body with a 1/4" port reaches 12.0 mm2 (Cv 0.67) if your cylinder is starving for flow at PT1/8. Mind the published reversal strokes: spool stroke is 2.0-3.3 mm and the selector travel is 5.1-6.4 mm. Exceeding these limits damages the valve, so fit a mechanical stop rather than letting an operator force the knob past its travel.
Frequently asked questions
It is a 5/2-way external control, direct acting valve with a black selector switch actuator and manual restoration. Operating 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 (40 um element). The port is PT1/8 on the 210 body, with an effective area of 9.0 mm2 (Cv 0.50). Body is aluminium alloy; no lubrication is required, though AirTAC suggests ISO VG32 if lubricated air is already in use.
The datasheet publishes a reversal stroke of 2.0-3.3 mm for the spool and 5.1-6.4 mm for the selector. These are hard limits: driving the knob past them damages the valve, and AirTAC states this explicitly. In practice, mount the valve so a panel or bracket forms a positive stop, and brief operators that the selector should never be forced at the end of its travel.
