The world of Vuototecnica valves is growing, welcoming the new EGN series.
These direct control, two-way valves are perfect for all cases in which suction must be controlled separately from the supply of air to the circuit, such as for degassers, autoclaves and vacuum heat sealers.
The materials are solid and of high quality: the body is in fact made from solid aluminium.
This is a substantial difference compared to competitors, who generally offer valves made from die-casting.
This is a construction choice that Vuototecnica has been applying to all its solenoid valves for years and that ensures the total absence of valve body micro-cracks, which are often present in the production processes of die-cast bodies.
The construction solution chosen by Vuototecnica ensures that residual operating pressures of 0.5mbar are reached and maintained.
EGN valves operate on the pressure differential existing between the pump or vacuum generator and the pressure of the sucked air, and by conveying this “differential pressure” to the servocontrol, through the actuator, the shutter is controlled without the need for compressed air or springs. This guarantees a very high switching speed in favor of high working cycles in emptying systems.
There is no comparison when comparing them to pneumatically actuated ball valves, which are widely used on the market in emptying processes. The actuation times of Vuototecnica EGN valves are half those of the most commonly used valves!
The electric coil is standard, fully plasticised in synthetic resin, watertight execution and 360° adjustable. The connector can be oriented 180° on the coil and can be supplied, upon request, with a luminous LED, with an anti-disturbance circuit and/or with protections against overvoltage and polarity inversion.
Finally, it is known that the choice of the solenoid valve should always be made according to the flow rate and the suction connection of the pump or vacuum generator. Two sizes are currently available, 1″1/2 and 2″gas, both with high volumetric suction capacity (230 and 490 mc/h suction flow rate) and therefore perfect in rapid emptying applications, for example in vacuum packaging processes.
They can be supplied in Normally Open or Normally Closed (NO-NC) version in order to guarantee to the final customer the operative flexibility.
