Indicador de Límite del Sistema de Presión de Gas

Question

En ArcFM classic hay un campo que puede estar presente en múltiples clases de dispositivos, y siempre en las clases que contienen reguladores y válvulas, llamado GASPRESSURESYSTEMSTATUS que indica si el dispositivo actúa como un límite del sistema de presión. Algunas empresas podrían tener un campo con otro nombre (como PARTITION) al que se le asigna un nombre de modelo para indicar que cumple esta función.<\/P> Supongo que hay un campo con un propósito similar en UPDM, pero no logro localizarlo. Cualquier orientación sería muy apreciada.<\/P> Gracias, Ed<\/P>

Hi Tom -

This is a really good point. I will need to check further into the legacy
data.

Thx,

Hi Ed,

Controllable valves rarely sit on the edge between two pressure zones of different pressures.  To allow a technician to open a controllable valve on the edge of two differing pressure zones, puts the equipment and customers within the lower pressure zone at risk of over-pressurization and system failure.

Within the natural gas industry there are some who refer to Regulators as Pressure Reducing Valves.  Since these are two terms referring to the same type of device, within UPDM we refer to these devices only as Regulators.

Is it possible your legacy dataset, has generically classified a regulator as a valve?

Hi Tom -

Thanks for the detailed response.   With this the path for regulator configuration is clear.

However, what of valves that sit between two pressure systems?  Are there expectations about asset group/asset type assignments for such valves?

Thanks again,

Ed
