Vacuum Generator, Multitasking / Manifold

Multi-function vacuum generator module VZ

RoHS2 Compliant

Small size and lightweight Vacuum Generator whose wiring for supply valve and air release valve is efficiently concentrated in one bundle.

Advantages

Small size and lightweight Vacuum Generator whose wiring for supply valve and air release valve is efficiently concentrated in one bundle.

Featuring a built-in vent valve, the VZ type vacuum generator sucks in atmospheric air and substantially reduces vacuum breaking time by large quantities of air.

The suction valve is offered in both single- and double -solenoid types.

Supply valve and blow-off valve can be powered by a single muti-pin connector.

Plug-in manifold with a multi-pin connector reduces wiring works.

The power consumption of solenoid valve is reduced to 0.55W for energy saving.

Vacuum port size can be chosen from φ6mm, φ4mm push-in fitting and M5 female thread.

A rich variety of vacuum sensors is offered to meet the needs of a wide range of applications.

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.
