Description
Ejector System
Vacuum Pump System
PV
Air pressure supply port
Compressed air supply for operating ejector
-
(Operating pressure range)
0.3 to 0.6 MPa
Note 1)
-
Vacuum pressure supply port
-
Vacuum source (vacuum pump)
(Operating pressure range)
-
0 to -100 kPa
PS
Pilot pressure supply port
-
Compressed air supply for pilot valve
(Operating pressure range)
-
0.3 to 0.6 MPa
PD
Individual release pressure supply port
Release pressure, Compressed air supply for individual setting (Option)
(Operating pressure range)
0 to 0.6 MPa
(PD ≤ PV)
0 to 0.6 MPa
(PD ≤ PS)
V
Vacuum port
For connecting adsorption equipment including pad
EXH
Exhaust port
Exhaust when ejector operates
Note 2)
-
PE
Pilot pressure exhaust port
Exhaust when valve operates
Note 3)
Note 1) For models without valve, pressure can be 0.3 MPa or less.(Ejector system)
Note 2) Manifold can be used at 0.3MPa or less when the manifold is for individual SUP. For 0.2Mpa or less, select K or J for the
valve type.
Set pressure as PV
≦
PS.
Note 3) For ejectors with silencer, air exhausts from A (slit on both sides). For port exhaust type, air exhausts from B.
Note 4) Pilot pressure for ejectors is exhausted from the ejector and the common exhaust. Vacuum pump system exhausts air from
PE port on the spacer. (Female thread type (M
3) is available by option “C” for PE port of the pump system.)
Male thread type can be selected by option [C] for PE port of vacuum pump system. When option [C] is selected for valve
type R, operating conditions below apply.
- Select the type with release pressure supply port (PD) as an option. Single unit / Manifold: Option (D)
Manifold: Option (P)
- Vacuum pressure for PV port: -60 to 100kPa
- Energization time for the relief pilot valve: 200ms or longer when the PD port is released to the atmosphere.
500ms or longer when the 0.1Mpa is supplied to the PD port.
If the product is used out of this operating condition, please contact your local sales office.
