*1 Refer to "Feedthrough" about relationship between vacuum level and feedthrough.
*2 Actuator < 60°C<140F>.
*3 NC = Normally closed (Valve automatically closes when compressed air released).
Operation system: Cylinder structure
The operation system can be selected from three types: "double acting cylinder", "single acting cylinder", and "manual".(0.10MPa) is supported.
Single-acting (normally closed)
Seal structure can be selected from "O-ring type" and "Bellows type".
- Feedthrough of VL□-SA is O-ring (FKM)shaft feedthrough, which endures particle.
- Feedthrough of VLP-U is O-ring (NBR) shaft feedthrough, which endures particle.
- Feedthrough of VL□-SB is bellows feedthrough, which minimize outgassing.
- Bonnet flange seal of VLP-MB is metal which makes possible to bake out at 200˚C (392F) in opening position.
The connection flange can be selected from four types: "JIS-VF", "ISO-KF", "ISO-K", and "ISO-CF". The flange size is 16A to 350A are made of SUS (O-ring is fluoro rubber: FKM).Large size over 500A is made of SS (O-ring is nitrile rubber: NBR)is unified
*1 Numerical number used for model is: ◆"Nominal diameter: A (ISO) mm", ◇ "Nominal diameter: A (conventional JIS) mm", ●"Nominal diameter: B inch".
|Position indicator type||Lead switch (double wire system, contact switch, cable length 1m (3.28 feet))||Lead switch (double wire system, contact switch, cable length 1m (1.64 feet))|
|Contact capacity of position indicator||DC24V/5～50mA
|Contact capacity of position indicator||Lead switch LED indicator|
|Valve mounting||No mounting||with mounting|
Recommended solenoid valve for valve operation
- <*>The old VLP solenoid valve can be used for the new valve.
- However, if the solenoid valve for the old VLP-U6, VLP-U14, and VLP-U14R is diverted to the new valve, the operation time may be slightly delayed.
※Selonoid valve are not available in the new lineup, please prepare by customer.
