Operate safely and reliably in highly oxidizing environments
Handling liquid and gaseous oxygen is challenging due to the risk of fire ignition. The industry needs solutions that deliver high level of performance, reliability and long service life while meeting stringent cleanliness requirements.
The Air Separation Process
In and around an Air Separation Unit (ASU), Liquid Oxygen (LOX), a direct product of the cryogenic distillation process, is handled prior to conversion into Gaseous Oxygen (GOX). This occurs in a heat exchanger, following which gaseous oxygen is distributed and used in blast furnace, chemical reactors and many other industrial applications. Often, these services face important reliability issues that impact plant productivity and, more critically, safety: a defective valve can result in a significant accident.
Reliable oxygen service valves must combine suitable material selection with the fulfilment of stringent cleanliness requirements to deliver outstanding isolation and control functions at cryogenic temperatures in LOX and high pressures in GOX.
Superior Oxygen Service Valve Design
Improve Safety
Rising stems and body cavities in traditional valve designs create risk of external particulate ingress and oxygen phase change with consequent potential for ignition. Furthermore, traditional gate, ball and high-performance butterfly designs experience mechanical friction during sealing which is another possible source of ignition.
Vanessa Series 30,000 for oxygen service combine suitable design features (full metal construction, frictionless quarter turn rotation, metal to metal torque seating) with an optimized material selection to safely deliver outstanding isolation and control functions in critical applications with enriched oxygen atmospheres.
