Festo – VABF-S4-1-V2B1…-D2 – 1212a English 41
1.2 Key features
– Vacuum module for use on the valve terminal VTSA/VTSA-F
– Solenoid valve for controlling vacuum generation (solenoid coil 12) and for controlling the ejector
pulse (solenoid coil 14) for accelerated vacuum reduction and safe placement
– Flow control screw for adjusting the ejector pulse
– Pressure sensor with switching output
– Solenoid valve switching status display via LED display
– Switching of the solenoid valve with mechanical manual override for vacuum generation
– The ejector pulse cannot be switched via the mechanical manual override when the power supply is
activated.
– In the absence of electric or pneumatic supply the valve reverts to the “create vacuum” setting if the
valve was in the “create vacuum” or “air saving” status.
– Non-return valves delay the reduction of the vacuum if the air supply is interrupted.
– Silencer
– Actuation and air supply via the valve terminal
– Electrical isolation between the valve terminal and vacuum module
– Vacuum module supplied with power via separate M12 plug, not via the valve terminal
– The vacuum module VABF-S4-1-V2B1 can be operated in combination with the vertical stacking for
pilot air switch-off (intermediate plate VABF-S4-1-S plus 5/2 way valve) on the valve terminal VTSA.
