3- and 5-spindle valve manifolds

for vertical angular differential pressure lines

■Overview

2

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.
