MD51

This slimline monoflange Differential Pressure close coupled manifold is designed to replace all standard valve assemblies which are usually needed for a differential pressure measurement into one single monoflange/manifold. It is a combination of the primary process isolation valve (OS&Y), a bleed, secondary valve and a double block/equalize/double vent configuration, all integrated in one piece body.

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

Connections

Per default: Vent and/or test ports will be 1/4” thread size. See ordering information on the back of this specification sheet for connection types available.
