■
Overview
These 3-spindle and 5-spindle valve manifolds 7MF9413-1..
were developed specially for vertical differential pressure lines.
The valve manifolds are used to shut off the differential pressure
lines and to check the pressure transmitter zero.
The 5-spindle valve manifold permits venting on the transmitter
side and checking of the pressure transmitter characteristic.
■
Benefits
• For vertical differential pressure lines
• Max. operating pressure 420 bar
• Transmitters of the DS series can be operated and read from
the front.
■
Application
The 3-spindle and 5-spindle valve manifolds for vertical differen-
tial pressure lines are for liquids and gases. The valve manifolds
are flanged on the pressure transmitter.
■
Design
All versions of the spindle valve manifolds have a process con-
nection ½-14 NPT.
The connection for the pressure transmitter is always designed
as a flange connection to EN 61518, form B .
The 2-spindle and the 5-spindle valve manifold have in addition
a vent and test connection ¼-18 NPT.

Function
Functions of all valve manifolds:
• Shutting off the differential pressure lines
• Checking the pressure transmitter zero
Additional functions of the 2-spindle and 5-spindle valve mani-
folds through the vent and test connection:
• Venting on the transmitter side
• Checking the pressure transmitter characteristic
