YT-700 series
2.8
Operation Logic – YT-700S (3 way)
As signal pressure is being supplied, the plunger (
○
6
) rises and creates secondary a gap
between the nozzle (
○
9
) and plunger (
○
6
) which results primary air pressure exhaustion.
When signal pressure has been turned off, the plunger (
○
6
) moves downward and blocks the
channel. At the same time, the air pressure will exhaust through the channel between the
plunger (
○
6
), vent (
○
2
), and body cap (
○
1
).
2.9
Operation Logic – YT-700D (4 way)
As signal pressure is being supplied, plunger (
○
6
) rises and creates a gap between the
nozzle (
○
9
) and plunger (
○
6
) which results primary air pressure to push down the spool (
○
11
)
and exhausts air to OUT2 (C2). When signal pressure has been turned off, the plunger (
○
6
)
moves downward and blocks the channel. At the same time, air pressure pushes spool (
○
11
)
upward and exhausts air to OUT1 (C1).
