Advantages
Realizing a high-cycle vacuum system.
The response characteristics of supply valve is maximized to realize a high-cycle vacuum system.
Three-port specification has been added to the lineup of external vacuum controller. By adopting a three-way vacuum supply main valve, vacuum release time is drastically shortened.
Since the conventional two-way valve (VXP type) operates to maintain the vacuum immediately after the main valve is shut off, only blow-off air contributes to releasing vacuum. In the newly commercialized three-port specification (VXPT type), however, the atmospheric pressure is introduced when shutting off the main valve to break vacuum using the atmospheric pressure and blow-off air.
A light weight and compact vacuum unit meeting market needs.
Two types of vacuum switch are prepared.
As for vacuum switch with good visibility LED display, 2 switch outputs type, analog output & 1 switch output type and low cost analog output type are available.
Two types of installation method are available depending on the applications.
Available in the specification for fields requiring "No copper-based metal material is used in airflow paths"and "Low-level Ozone resistance".
No copper-based metal material is used in airflow paths, and sealing rubber is designed to be resistant to low-level ozone.

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."
