MP00 – Double flange

This slimline monoflange is designed to replace the primary and secondary Process valve assemblies which are usually needed on remote seal (P and dP) pressure measurements. It is a combination of the primary process isolation valve (OS&Y), an optional bleed and optional secondary valve, and an integrated drip ring, all integrated in one piece body. The main advantages are less leaking points, weight saving and reduction in installation and maintenance time and costs.


As 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.
