How to swap location of a Rolamite valve
This video shows how to change the position of a large Rolamite valve on an Alicat mass flow controller (part numbers beginning with MCR) or pressure controller (part number beginning with PCR). You can either switch the valve from upstream to downstream, or vice versa.
The procedure takes about 10 minutes. While it is not highly technical, it is best performed by an experienced technician.
