SITRANS P measuring instruments for pressure

Fitttings - Shut-off valves for differential pressure transmitters

Valve manifold combination DN 5/DN 8

2/212

Siemens FI 01 · 2009

■

Overview

The valve manifold combination DN 5/DN 8 (7MF9416-6..) is for

pressure transmitters for differential pressure.

The combination is used to shut off and blow out differential

pressure lines and to test the pressure transmitter zero.

In the designs with a test connection, a test device can be con-

nected to test the pressure transmitter characteristic.

■

Benefits

• Max. working pressure 420 bar

■

Application

The valve manifold combination DN 5/DN 8 is designed for va-

pors.

■

Design

The valve manifold combination DN 5/DN 8 has a process con-

nection with welding pins.

The connection for the pressure transmitter is designed as as

flange connection, while the blow-out connection is designed as

a pipe union with ferrule.

The manifold valves have an internal spindle thread, while the

blow-out valves have an external spindle thread.

The optional test connections are M20x1.5.

Materials used

Function

• Shutting off the differential pressure lines

• Blowing out the differential pressure lines

• Checking the pressure transmitter zero

As an option it is possible to order a version with a test connec-

tion, to which a test device for checking the transmitter charac-

teristic can be connected.
