Description of the pressure gauge manifold
With upstream pressure equalising valves it is possible to achieve uniform pressure loading from the "+" and "-" side, to avoid single-sided overpressure loading during both start-up and operation, and also to enable zero point checks during operation.
These pressure gauge manifolds, with interposing or integrated shut-off valves, enable the isolation of processlines without interruption to the operation, an instrument to be removed, tested, shut-down, protected against inadmissible pressure overload as well as the measurement of staticpressure (after dismounting the differential pressure measuring instrument).
Four-way and five-way valves
Furthermore, these pressure equalising valves, with integrated shut-off, purge and vent valves, enable the pressure gauge to be vented on one or both sides and the supply line to be purged.
