Vacuum generator / ejector
1/8" - 3/8", 120 psig | VV series Partek Division

The Venturi/Vacuum Generator is designed for corrosive or high purity gas applications. The design consists of two machined high purity PTFE body halves attached using a tongue and groove sealing mechanism. The concept of a venturi valve is a short tube with a tapered constriction in the middle that causes an increase in the velocity of flow of a fluid and a corresponding decrease in fluid pressure. This is used in measuring flow or for creating a suction. The lack of moving parts eliminates the possibility of media contamination.

FEATURES:

Integral nozzle on inlet body half eliminates the need for calibration and realignment.
PTFE wetted surfaces eliminates contamination and fluid compatibility issues.
