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.
