Gas inlet two-channel sytem INJECT

Product Description

The device is intended for remote control of gas inlet in ion – vacuum installations.

In operation with various ion- vacuum installations there is a necessity of dosing gas inlet in working chambers. One of the most simple and reliable devices serving for these purposes is two-channel system of gas inlet INJECT.

In the devices having a feedback, it allows:

  • To automatically support the set pressure;
  • To choose polarity of a signal of a feedback and to shift its phase on 180oС;
  • To change time constant of the amplifier of a feedback.

For unlocking the valve in system it is applied piezostriction device providing remote control for inlet valve, work in modes “yes” and “no” as well as modulation of a gas stream.

Presence of two valves enables to carry out both serial and simultaneous inlet of two gases.

The dosing pair of inlet valve: stainless steel – oxygen-free copper .
