The use of the valve block with inlet and outlet valves allows simple
installation and setup of the differential pressure transmitter. The valve
block separates the differential pressure transmitter from the process
side and enables simple maintenance and checking of the measure-
ment loop. The integrated equalization valve ensures the same
pressure conditions on the plus and minus side during setup. The five-
fold valve block contains also two valves for checking/ventilating the
differential pressure transmitter after it is installed.
The valve block is used for direct connection to the differential
pressure transmitter. The following figure shows the connection of a 5-
fold valve block.
