MP21 SBB/DBB slimline monoflange with "Half DIN/IEC"

This slimline monoflange is designed to replace the primary and secondary Process valve assemblies which are usually needed for absolute or gauge pressure instruments with a Half DIN19213 / IEC61518 (no atmospheric port) connection. It is a combination of the primary process isolation valve (O.S.&Y), an optional bleed, optional secondary valve functional as a 2-valve manifold, all integrated in one body.

The main advantages are less leaking points, weight saving and reduction in installation and maintenance time and costs.

This manifold is standard produced in AISI316 material, but "exotic" materials are also available.

Maximum working pressure is 420 Bar
Maximum temperature is 200°C


Vent and/or testports will always be 1/4" threadsize, independent of process connection sizes.

For ordering information please consult the Model Code Wizard for port connection types available.
