Valves for severe service

A model number alone cannot confirm whether a valve is suitable. Selection also depends on the process fluid, temperature, pressure, cycling frequency, sealing requirements and installation.

We support enquiries for ball valves, metal-seated valves and specialist shut-off and globe valves. The manufacturer confirms the design and materials for the specified operating conditions.

IVT lists PTA production among its applications. Valve selection depends on the process stage, fluid and operating cycle. Powder and slurry duties may require consideration of particles, deposits, crystallisation and wear.

Send the valve tag, process location, fluid composition, operating conditions, cycling frequency and any existing drawings or data sheets. IVT confirms the appropriate design, sealing arrangement and materials.

IVT offers valves in special materials and designs tailored to customer requirements. Its literature lists titanium, zirconium, Hastelloy, Monel, nickel-based alloys and duplex stainless steel. The appropriate grade and valve design depend on the process fluid and operating conditions.

IVT delivery records refer to Inconel, Incoloy and Monel as distinct material families. Specify the body, trim and seat materials separately. A past supply record does not establish suitability for another application.

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.

• Process fluid composition, concentration and changes in operating conditions
• Operating and design temperatures, pressures and differential pressure
• Specified materials, or the materials currently in use and any problems
• Connection drawings, available installation space and any custom design requirements

If a valve is leaking internally or operating incorrectly, include its current configuration, any changes in operating conditions and its maintenance history. This information helps the manufacturer assess the problem before a repair or replacement is considered.
