Fitttings - Shut-off valves for differential pressure transmitters

3-way and 5-way valve manifolds DN 5

■Overview

2

■Function

•Shutting off the differential pressure lines

•Checking the pressure transmitter zero

•In addition, the five-way valve manifold permits blowing out of the differential pressure lines.

The three-spindle and five-spindle valve manifolds DN 5 (7MF9410-1../-3..) are used to shut off the differential pressure lines and to check the transmitter zero.

In addition, the five-way valve manifold permits blowing out of the differential pressure lines.

■Benefits

•Available for aggressive and non-aggressive liquids and gases

•Max. working pressure 420 bar, with version for oxygen max. 100 bar

■Application

The 3-way and 5-way valve manifolds are 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 process connection of the 3-way and 5-way valve manifolds is a pipe union with ferrule.

Both valve manifolds have 2 flange connections for connecting a pressure transmitter.

In addition, the five-way valve manifold has 2 blow-out connec- tions.

Depending on the version the valve manifold has either 3 or 5 valves, each with an internal spindle thread.
