Description

This compact H-model 4-valve double isolate/double separated vent manifold is designed to accommodate any DIN19213 interface compliant differential pressure transmitter.
This manifold is standard produced in AISI316L material, but "exotic" materials are also available.
The main advantages are less leaking points, weight saving and reduction in installation and maintenance time and costs.

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

Connections

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