3.3.3 The 32003 insertion/extraction valve

The ORBISPHERE 32003 insertion/extraction valve allows for sensor removal and installation
without having to drain the fluid in the line. It can withstand a pressure of up to 20 bars, with the
sensor in place or not. Refer to
Sensor insertion is made by inserting the sensor into the housing and tightening the retaining collar
until it stops. As the retaining collar is tightened, the valve will open to allow the sample to flow past
the sensor head. Remove the sensor by unscrewing the collar and pulling the sensor out. As the
collar is unscrewed, the valve will automatically close to avoid any sample spillage.
The diagram above right, shows the sensor in a sample line with the valve open allowing the sample
to run past the sensor head.
