3 types for supply valv

Wide variety of combinations can cope with variousneeds.

External Vacuum Controller for Vacuum Pump Series is for

available

For the pipe lead-out direction of concentrated piping of

manifold-type, two types are available; front lead-out

typeand rear lead-out type.

It is designed to adjust the breaking flow and breaking pressure at the same time to prevent scattering or locking of work

piece which is difficult to control by only breaking flow adjustment.

By adding a relief function to the vacuum breaker circuit, the vacuum breakdown time has been shortened for the first

time in the industry.

The vacuum sensor is an LED-indicated digital sensor (V4).

The basic specification : 2 switch output and analog output

Standard nozzle bore: 05(ø0.5mm), 07(ø0.7mm), 10(ø10mm) and 12(ø1.2mm).

Doble solenoid type

(Vacuum retention type, selectable for saving energy)

Normally closed type

Normally open type

- Built-in Spring type check valve.

- Stable long time check.

- Vacuum ON / OFF can be performed in one operation when energy saving sensor is used.
