Airtac M5Y Rocker Type Mechanical Valve M5Y21006G
Mechanically actuated · no coil, no pilot airThe AirTAC M5Y Rocker Type Mechanical Valve M5Y21006G is a genuine 5/2-way lever type control valve. A lever that STAYS where it is set - manual restoration, so it holds the circuit. 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 lever 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 M5Y21006G
The M5Y21006G is a 5/2 way external control, direct acting valve that is thrown by hand - there is no coil, no wiring and no pilot port, so it is not a solenoid valve (that is the 4V family) and it is not the air-piloted 4A family. A green hand lever operates the spool, and because the Y version has manual restoration, the valve stays in whichever position you leave it until you physically move the lever again.
This is the 210 body (200 series single control) with PT1/8 ports and a 9.0 mm2 effective area (Cv 0.50). The sliding-column spool means changeover is not affected by working pressure - there is no back-pressure effect, so the valve switches the same way from low pressure up to full line pressure. The Y lever runs a metal control set for long, stable service, the exhaust sits on top of the body so a silencer screws straight on, and the body can be surface-mounted or panel-mounted.
Typical applications
Drill jig clamp hold
At a drilling fixture, the operator flips the green lever once to close a swing clamp on a steel bracket and the valve holds that state through the whole cycle - no spring can creep it back, and one flip releases the finished part.
Cartoner format change
On a cartoning line, the lever isolates air to the filling head while operators swap tooling between carton sizes; because it stays put, nobody re-flips it mid-change and air cannot creep back to the head.
Grain auger gate control
On a farm feed trailer with no electrics on board, the lever drives the slide-gate cylinder over the auger; the operator opens the gate at the shed and closes it in the field, with the valve holding each position between moves.
How to choose
You are really choosing between the three manual-restoration actuators in this family. The HS selector turns and stays and suits a panel face; the PL latching button presses in and twists to release and is red only; the Y lever gives you a green grip you can flip with a gloved hand while watching the machine, which is why it is the usual pick at the machine side. If the valve should spring back on release instead, step to the D short handle or the B plunger. Body-wise, a 110 version of this valve flows 8.0 mm2; this 210 body gives 9.0 mm2 on PT1/8, and stepping to the 210 in 1/4in lifts flow to 12.0 mm2 (Cv 0.67) - size the port to the cylinder, not to the fitting you happen to have. Mind the reversal stroke: AirTAC publishes a narrow stroke window for every actuator in this family and states plainly that exceeding it damages the valve, so move the lever by hand through its natural travel and never force it past its stop.
Frequently asked questions
It is a 5/2 way external control, direct acting valve with a green hand lever and manual restoration. Ports are PT1/8 and the effective orifice is 9.0 mm2 (Cv 0.50). Pressure range is 0-1.0 MPa (0-145 psi) with a proof pressure of 1.5 MPa (215 psi). Media is air filtered by a 40 um element, at -20 to +70 C. The body is aluminium alloy, and lubrication is not required - if lubricated air is already in use, keep the same medium (AirTAC suggests ISO VG32 or equivalent) to optimise valve life.
No. Manual restoration means the lever stays wherever you set it, independent of line pressure, and because the sliding-column spool has no back-pressure effect, the changeover force is not affected by working pressure - switching feels the same at low pressure as at full line pressure. If you ever need a spare, the control sets in this family can be ordered separately rather than replacing the whole valve.
