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.
