clarify the cause of the failure and take
countermeasures appropriate for the cause.
Air leakage
1. Between valve and base
1-1) Looseness of clamp screw
or mounting bolt.
Give more torque to clamp screw.

If the damage is seen on the gasket,
replace with new gasket.
1-2) Caught gasket
Replace with new gasket.
1-3) Intrusion of foreign matter
To remove foreign matter by air blow
of piping and when a gasket
damaged, replace with new gasket.
2. Air leaks through One-touch fitting
2-1) Tube is not inserted
enough deeply.
2-2) Tube has a flaw.
2-3) Tube is cut diagonally.
Check these items and replace part
and re-wire positively.
2-4) Packing of one touch
fitting is damaged.
Replace with one-touch fitting.
3. Air leaks through exhaust port (R port)
Note) The valve with metal seal allows air
leakage from main valve approx. 200Ncc for
each port ( at 0.5MPa). The air leakage within
the range should not be considered abnormal.
3-1) Looseness of clamp screw
or mounting bolt.
Give more torque to clamp screw.

If the damage is seen on the gasket,
replace with new gasket.
3-2) A foreign material included
into supplied air is caught by
the
main
valve
and
increases
internal
air
leakage.
Replace with new valve.
Clean the supplied air.
4. Air leaks through manifold.
Insufficient bolt tightening
After stopping air and re-tighten the
bolts.
Confirm there is air leakage.
