Safety Data Sheets
Le guarnizioni a membrana 740 e 741 a dislocamento elevato sono ideali quando la misurazione della bassa pressione e la protezione dei processi sono un fattore fondamentale:
Mercato dei processi:
Petrolio e gas
Raffinerie
Chimica e petrolchimica
Acqua e acque reflue
Applicazioni di processo:
Fracking petrolio e gas
Processi conformi NACE (Separazione dei gas acidi)
Biogas e Biodiesel
Caratteristiche principali
La porta di lavaggio (opzionale) facilita la pulizia e il lavaggio dei fluidi di processo soggetti a intasamento.
Diaframma saldato allargato; l'elevato spostamento consente un'alta sensibilità alle fluttuazioni di pressione
