Function/Application
E
Vacuum break
flow adjusting
needle
Screwdriver
operation type
long lock nut
· Used when the port position is close to the manifold’s
individual supply and needle adjustment is diffi cult
J
Round lock nut
· Thicker than the standard hexagon type
· More suitable for hand tightening
· The round lock nut improves operability when the manifold or exhaust port type is used.
K
Screwdriver
operation type
· The slotted type allows for fi ne adjustment when the manifold
or exhaust port type is used.
L
Manifold individual
supply specification
· For adjusting the manifold’s supply pressure and the vacuum
pressure reached by each ejector individually
P
With manifold common release
pressure supply (PD) port
· When selecting option “D” (with common release pressure
supply (PD) port), a pressure which is different from the
common PV can be supplied to the common PD.
W
With exhaust interference
prevention valve
· When ejectors are operated individually, exhausted air may fl ow
backward from the V ports of ejectors that are turned off. The
exhaust interference prevention valve prevents this backfl ow.
Specify the valve manifold and mounted valve part numbers as well as the ejector manifold
and mounted ejector part numbers for ordering. Refer to page 120 for an order example.

For adequate perfor-
mance, the number
of stations that can
be operated simulta-
neously depends on
the nozzle diameter.
