SITRANS P measuring instruments for pressure
Fitttings - Shut-off valves for gage and absolute pressure transmitters
2-way valve manifolds DN 5
■
Overview
2
The two-way valve manifold DN 5 (7MF9401-2..) is used to shut
off and vent the line with the measured medium, and to test the
connected pressure gage or transmitter.
■
Benefits
• Available for aggressive and non-aggressive liquids and
gases
• Two connection versions available
- For flanging to pressure transmitters
- With nipple for connection of pressure gages and pressure
transmitters for pressure
• Max. working pressure 420 bar, with version for oxygen max.
100 bar
■
Application
The 2-way valve manifold is available in versions for aggressive
and non-aggressive liquids and gases.
Mounting plates are available for wall mounting, for securing to
mounting racks or for pipe mounting.
■
Design
The 2-way valve manifold DN 5 has 3 connections:
• A process connection (pipe union with ferrule Ø 12 mm)
• A connection for a pressure gage (flange or nipple)
• A test connection (thread G
The 2-fold valve manifold DN 5 also has an operating valve and
a test valve, each with an internal spindle thread.

Function
The characteristic of the pressure measuring instrument or pres-
sure transmitter can be tested through the test connection.
A pressure gage for local display can be connected to the test
connection.
The two-way valve manifold DN 5 can be used in addition to shut
off and vent the line with the measured medium.
