Installation & Commissioning

Mounting Guidelines

The PMP71B can be installed via:

Direct thread connection — G½ … G2, R½, MNPT¾ … MNPT2, FNPT½, R½

Flange mounting — DIN, ASME, JIS (DN25 … DN100, NPS 1″ … 4″)

Pancake seal connections — 2″ … 4″, DN50 … DN100

Diaphragm seals — For extreme temperatures, corrosive media, or viscous fluids

Using a valve manifold allows for easy commissioning, installation, and maintenance without interrupting the process. The OPL (overpressure limit) for the device depends on the lowest-rated element of the selected components — the process connection must be taken into consideration in addition to the measuring cell-2.
