Vacuum Generator, Multitasking / Manifold
Multi-function vacuum generator module VJ
By newly adding pressure adjusting function to blow-off flow adjusting function, it enables to prevent works from being-blown away.

Advantages
By newly adding pressure adjusting function to blow-off flow adjusting function, it enables to prevent works from being-blown away.
By newly adding pressure adjusting function to blow-off flow adjusting function, it enables to prevent works from being-blown away.
Shorter vacuum release time is realized.
A relief mechanism (extra pressure is relieved) is built in the blow-off circuit.
Supply valve is available in three different types.
Power saving double solenoid type (retention type) is optimal for applications where vacuum is generated for a long period of time.
LED vacuum switch allow for clearer visual recognition.
Two types of vacuum switches are available, two switch outputs, or analog & one switch output, to be selected depending on the desired application. For wiring, a connector wire is adopted to enhance the ease of designing the wiring layout.

Detailed Safety Instructions
Warning
1.For the double-piloted valve type, the switchover valve is in the state of neutral when the supply of both pilot air to the switchover 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 double piloted valve type under a vibration, install the vacuum generaor placing the switchover valve (main valve) at a right angle to the direction of vibration
3.Tighten screws with appropriate tightening torque referring to the digital catalog. Improper tightening may cause an air leakage, a falling off of the product or damages to the product.
