Valve manifold combination DN 5/DN 8

■Overview

2

■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.

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.
