Vuototecnica two- and three-way vacuum solenoid valves: maximum suction flow, high cycle rates, the best sealing and small dimensions


Making the most of vacuum sources flow rate is necessary but that almost never happens. In fact, we find generally solenoid valves converted for compressed air, for the management of vacuum opening and closing, with the result that the intake passages are undersized and unsuited for the task.

Vuototecnica two- and three-way vacuum solenoid valves, instead, have an inner section that allows increased passages, calculated specifically for the vacuum management.

These solenoid valves are designed to manage the vacuum, with 2/2 and 3/2 configuration, with 1/4″-3/8″ and 1/2″ gas intake sections, and they are available in normally closed configuration. To allow the opening you have to energize them. Vacuum distribution bodies are obtained from solid aluminum, to ensure the seal without equal, even in presence of residual pressure with values that are lower than the 0,5mbar.

4_017The biggest advantage is that they allow a very high number of cycles per minute, because the electric coil acts directly on the core of the solenoid valve internal structure. The solenoid valve shutter can be in NBR or in Vulkollan® and it is an integral part of the actuator movable core.

The two-way solenoid valves have both orifices of the same size, while the three-way solenoid valve all have the discharge orifice with a diameter of 3 mm, for it is obtained through the the steerer.

They all have very compact dimensions, a plus in all applications where it is necessary to limit the overall dimensions of the handling heads, or in the case of vacuum circuit installed in confined spaces.
