Oxygen shut-off valves for high-cycle service

Contact us to discuss a new oxygen shut-off application, check an existing IVT valve or review internal leakage and operating problems. If you do not have the full model number, start with the information available.

Selection requires more than oxygen purity and pressure. Temperature, differential pressure during operation, cycling frequency, actuation, connections, and project-specific cleaning and inspection requirements also need to be checked.

NEEDE supplied IVT ball valves to a coal-chemical plant where existing oxygen shut-off valves had suffered damage and internal leakage under frequent cycling.

The available records confirm supply, but do not verify subsequent leakage performance or service life. Valve selection for another plant requires a separate review of its operating conditions.

IVT is responsible for confirming the valve design, materials and suitability for your application. NEEDE helps you prepare the technical requirements, works with IVT on product selection and supports procurement and supply.

For an existing installation, send the valve details, observed symptoms and maintenance history. We can then clarify whether you need a quotation, a configuration check or further technical review.
