DN 8 3-way valve manifolds производства Siemens

The 3-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.

• For aggressive and non-aggressive liquids and gases
• The maximum working pressure is 420 bar (6092 psi).

For the process connection on the version for non-aggressive media it is possible to choose between a pipe union with ferrule and welding pins.

The version for aggressive media always has a pipe union with ferrule.

Both versions are available optionally with a test connection M20x1.5.

The valves have an internal spindle thread.

Materials used

3-way valve manifold DN 8, permissible working pressure as a function of the permissible working temperature

The 3-way valve manifold DN 8 performs two functions as standard:

• Shutting off the differential pressure lines
• Checking the pressure transmitter zero

All versions are also available with a test connection, to which a test device for checking the pressure transmitter characteristic can be connected.
