SITRANS P measuring instruments for pressure

Fitttings - Shut-off valves for gage and absolute industrial pressure transmitters

2-way valve manifolds DN 5

I Overview

Function

The characteristic of the pressure measuring instrument or pressure industrial 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.

■ 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 industrial racks or for pipe mounting.

Design

The 2-way valve manifold DN 5 has 3 connections:

• A process connection (pipe union with ferrule 0 12 mm)

• A connection for a pressure gage (flange or nipple)

• A test connection (thread G³/₈)

The 2-fold valve manifold DN 5 also has an operating valve and a test valve, each with an internal spindle thread.
