■
Overview
The 2-spindle, 3-spindle and 5-spindle valve manifolds
7MF9411-5.. are for pressure transmitters for absolute pressure
or differential pressure.
The valve manifolds are used to shut off the differential pressure
lines and to check the pressure transmitter zero.
The 2-spindle and the 5-spindle valve manifold enable in addi-
tion venting on the transmitter side and checking of the pressure
transmitter characteristic.
■
Benefits
• Max. working pressure 420 bar
• Each available in version for oxygen
■
Application
The spindle valve manifolds DN 5 are designed for liquids and
gases
Each is available in a version for oxygen on request
■
Design
All versions of the valve manifolds have a process connection 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.
The valves have an external spindle thread.

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
