Airtac M5C Long Handle Mechanical Valve M5C21006G
Mechanically actuated · no coil, no pilot airThe AirTAC Airtac M5C Long Handle Mechanical Valve M5C21006G is a genuine 5/2-way long handle type control valve. A long hand lever for operating force and reach. 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 long handle 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 M5C21006G
The M5C21006G is a 5/2-way external control, direct acting valve that is thrown by hand. There is no solenoid coil, no pilot port and no wiring: a long lever swings the spool, and when the hand comes off, the internal spring throws the valve straight back to its rest position. That makes it the valve for control stations where electricity is unavailable, unwanted or unsafe - a pure air circuit driven by a person's arm. The C actuator is a metal control set, so the lever is built to take deliberate, forceful operation rather than delicate button pressing.
This is the 200 series single control body (210) with a PT1/8 port and an effective area of 9.0 mm2 (Cv 0.50), finished with a green button cap on the handle. Because the spool is a sliding-column design, the force needed to change over is not affected by working pressure, so the lever feel stays consistent anywhere from 0 to 1.0 MPa. The exhaust outlet sits on top of the body, so a silencer screws straight in, and the valve can be fixed either by its body or through a panel cut-out.
Typical applications
CNC fixture clamp changeover
Mounted at the side of a machining centre, the long lever lets an operator swing the valve to clamp or unclamp a pneumatic vise in one motion. The spring return sends the fixture to its safe unclamped state the moment the hand leaves the handle.
Trailer tipper body control
On a tipper trailer or dump body, a cab-mounted long handle gives the driver reach and leverage to divert air to the hoist cylinder, then let go. The spool springs back and the body settles down under spring-restored exhaust flow.
Reject gate on a packaging line
At the end of a carton line, an operator trips the long lever to divert a reject piece into a bin. The handle's reach means the lever can sit outside the guarding line, and the spring return re-arms the gate for the next pass automatically.
How to choose
The nearest neighbour is the M5D short handle type. Both are spring-return levers, but the D suits shallow panels and tight enclosures, while the C's long handle gives you reach and leverage - use it where the operator stands at a distance, works with gloves, or needs to swing the valve without hunting for it. If the state must hold without a hand on it, look instead at the M5Y lever or M5HS selector, which latch in position rather than spring back. On body and port: the 110 body is the lighter single-control option at 8.0 mm2 (Cv 0.45), while stepping this 210 body up to a 1/4" port raises flow to 12.0 mm2 (Cv 0.67) - size that to the cylinder bore you are driving. Note the colour code (here green) only exists on the 210 body, which is handy for telling stations apart. Respect the reversal stroke: spool travel is 2.0-3.0 mm and full handle movement is 11.0-16.0 mm. Exceeding these limits damages the valve, so fit a stop if the operator can over-travel the lever.
Frequently asked questions
It is a 5/2-way external control, direct acting valve with a long handle lever and automatic spring return. Port: PT1/8. Effective area: 9.0 mm2 (Cv 0.50) on the 210 body. Working pressure: 0-1.0 MPa (0-145 psi). Proof pressure: 1.5 MPa (215 psi). Temperature: -20 to +70 C. Medium is air filtered by a 40 um element; lubrication is not required, but once lubricated air is used, continue with the same medium (ISO VG32 or equivalent grade) to optimise valve life.
The spool only needs 2.0-3.0 mm of travel to change over, while the handle moves 11.0-16.0 mm in total. These are published limits, and AirTAC states explicitly that exceeding them damages the valve. Because the C is a long handle with real leverage, it is easy to over-swing - mount it so the lever hits a mechanical stop at the end of its travel rather than letting the operator force it past the limit.
