Advantages
Blow-off pressure control is available.
Pressure adjusting function is added to conventional blow-off flow adjusting function. It enables to prevent works from being blown away.
Realized shortening of blow-off time.
A relief mechanism (extra pressure is relieved) built into the blow-off circuit.
Supply valves are available in three different types.
Double solenoid type (vacuum retention type), which contributes energy saving, is suitable for a special application where continuous vacuum generation is required for a long time.
An LED display is adopted for the vacuum switch. Improved visibility.
Two types of vacuum switches are available, 2 switch outputs and analog output, with selection depending on the application.
For wiring, a connector wire is adopted to enhance the ease of designing the wiring layout.

Ordering Information
Detailed Safety Instructions
Warning
1.For the double solenoid type, the state of the switching valve is neutral when the supply of both pilot air to the switching valve for vacuum generation is stopped, or at the beginning of use after shipment. When resupplying pilot air, be sure to input a signal to the pilot valve or manually operate to position the switching valve in the required state before using it.
2.When using the double solenoid type in vibration, install it so that the vibration direction is perpendicular to the operating direction of the switching valve (main valve).
3.All screws must be tightened to the correct torque referring to the instructions. The tightening torque for the mounting of the product is given in "How to fix the product", and for the filter cover is given in "Replacement Element" of Vacuum Generator VJ. Failure to tighten to the correct torque may result in air leaks, product detachment and damage to parts of the product.
Caution
1.When replacing a supply port block, make sure not to lose the seal rubber and remove any foreign deposits in the vicinity, and securely tighten the screws with a torque of 0.27 to 0.3 Nm.
Frequently Asked Questions for External Vacuum Controller Series
VUS011-NW and FVXS-DW-1 are not the type of the product itself, but the type of "sensor" installed in the product. The official model code of the product is laser marked (or labeled) on the body. FVUS011-** is the sensor for Vacuum Generator VK, and FVXS-** is the sensor for Vacuum Generator VX (External Vacuum Controller VXP / VXPT).
The type of our vacuum generator complex type (External Vacuum Controller) starts with "V". (VG ..., VQ ... etc.)
The sensor model code may start with FV ... and may be written as [PRESSURE SWITCH].
The sensor model code is described only in the specifications with a sensor.
Both types indicate the valve position when the valve is unactuated. (normal position).
Normally closed type (N. C.)
Normal position is closed, covering a valve . When the valve is actuated, or electricity flows, the valve opens.
Normally open type (N. O.)
Normal position is open, uncovering a valve. When the valve is actuated, or electricity flows, the valve closes.
With the valve unactuated, the entrance leads to the exit.
There are two ways of measuring pressure, absolute pressure and gauge pressure.
Absolute pressure
Absolute pressure is zero-referenced against a perfect vacuum.
It is commonly used to measure flow rate.
When indicated, "abs" is inserted following the unit, for example 10 kPa abs.
Gauge pressure
Gauge pressure is zero-referenced against ambient air pressure.
It indicate how much pressure per １cm2 is against the ambient air pressure. It is commonly used for indication of manometer. When the pressure is over the ambient air pressure, it is called "positive pressure" and when it is under the ambient air pressure, it is called "negative pressure."
