Vacuum Chamber and Components – Flange Connections

Within Scitek we provide high quality vacuum components such as flange connections. Our product range includes weld flanges, copper seals, weld neck flanges, rotatable flanges and soft start valves.

Soft-start throttle valves

Consist of two halves of throttle flaps supported on a common axis and maintained in the open position by a spring. The axis is held in an ISO-KF centering ring that is formed as a body with valve seat. When mounting them between two ISO-KF flanges (instead of a centering ring), the open flaps must be orientated against the air flow in the vacuum line.

When the roughing system goes into operation, a strong air flow occurs in the forevacuum line, which immediately closes the valve and reduces the pipe section by about 99%. When reaching a differential pressure of approx. 15 mbar, the valve opens abruptly and leaves the pipe section nearly unobstructed for further pumping.
