Airtac M5HS Selector Mechanical Valve M5HS21006R
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5HS Selector Mechanical Valve M5HS21006R 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 M5HS21006R
The AirTAC M5HS21006R is a 5/2 way external control, direct acting valve operated entirely by hand: you turn its red rotary selector and the valve holds that position until a person deliberately turns it back. There is no solenoid coil and no pilot port anywhere in the construction, so nothing here needs a wire - this is hand-valve territory, not the 4V solenoid family and not the 4A air-pilot range.
It sits on the 200 series single-control body with a PT1/8 port and gives an effective area of 9.0 mm2 (Cv 0.50). Because the sliding-column spool is unaffected by back pressure, the effort needed to twist the selector stays consistent right across the 0-1.0 MPa working range. The exhaust outlet is on top of the body, so a silencer screws straight on, and the valve can be surface mounted or panel mounted as the station requires.
Typical applications
Mode select on a carton sealing line
Panel-mounted beside the start buttons of a carton sealer, the red selector diverts supply between the automatic cycle circuit and a slow jog circuit. Twist it to jog during jam clearance and it stays there until an operator turns it back - no spring can snap the line out of manual mode uninvited.
Tool-change isolation on a mould clamping fixture
Turn the selector to isolate the clamp circuit of an injection mould fixture while dies are swapped, then twist it back to re-pressurise. Restoration is manual, so only the operator's hand re-opens the circuit - there is no signal loss or failed pilot to worry about in a purely pneumatic cell.
Set-up hold on a pneumatic assembly press
During commissioning of an assembly press, technicians hold the rig in a fixed state with the selector while fixtures and parts are aligned. The station needs no wiring at all, so it works in the electricity-free corner of the shop where the rest of the logic is air-over-air.
How to choose
Three hold-type actuators sit side by side in this family: the HS selector you twist, the Y lever you throw, and the PL button you press and then release by turning. The HS earns its place when the machine state should be readable at a glance - knob in line with the panel label means one circuit, turned across means the other - which a flicked lever cannot signal as cleanly. If operators prefer a fast throw to a deliberate quarter-turn, choose the Y instead. Stepping from the 110 body to this 210 body raises the effective area from 8.0 to 9.0 mm2, and the 1/4 in 08-port version of the 210 reaches 12.0 mm2 (Cv 0.67) for larger cylinders. Do not drive the selector past its 5.1-6.4 mm actuator stroke: the spool needs only 2.0-3.3 mm of travel to reverse, and forcing the knob beyond its end stop damages the valve.
Frequently asked questions
It is a 5/2 way external control, direct acting valve with a red rotary selector on the 200 series single-control body. Working pressure is 0-1.0 MPa (0-145 psi), proof pressure 1.5 MPa (215 psi), media temperature -20 to +70 C using air filtered to 40 um, port PT1/8, effective area 9.0 mm2 (Cv 0.50), aluminium alloy body, no lubrication required.
The published actuator stroke is 5.1-6.4 mm and the spool itself moves only 2.0-3.3 mm to reverse the valve. AirTAC states explicitly that exceeding these limits damages the valve, so stop the knob at its end stop rather than forcing it. Also note the HS control set is engineering plastic and is for hand operation only - switching it by striking with a tool is expressly forbidden in the datasheet. Matching spare control sets can be ordered separately if a knob or set ever needs replacing.
